Profab Machine makes custom stainless steel clamps in 304 and 316L, including T-bolt, V-band, and tri-clamp types, to your drawing or sample. We CNC machine the flanges, bolts, and bridges. Polishing, passivation, and electropolishing are also available when the joint needs them. To start, send the hose or pipe diameter, the flange or ferrule type, and the grade. We will confirm the clamp style before quoting.
A stainless steel clamp is a band, ring, or bolted strap that holds a hose, pipe, or flanged joint together by squeezing it. A T-bolt clamp tightens around a hose, while a V-band clamp pulls two matching flanges together. A tri-clamp holds a gasketed ferrule joint that opens for cleaning.
Stainless steel is chosen where salt, washdown water, or heat would corrode a zinc-plated clamp. The grade and the clamp type both depend on the connection.
The clamp type depends on what it joins. Choose a T-bolt, worm gear, or spring clamp for a hose over a spigot, and a V-band clamp for a flanged exhaust or pipe joint. A tri-clamp suits a ferrule joint that must open for cleaning. We make each type to your drawing or sample.
A T-bolt clamp has a wide band and a bolt with a bridge, so it spreads the clamping load around the hose. We machine the T-bolt, bridge, and nut to your drawing. A T-bolt clamp suits turbo, charge-air, and coolant connections on modified cars, racing cars, and UTVs.
A V-band clamp pulls two matching flanges together, so the flange profile and diameter must match the clamp. We machine V-flanges from stainless bar to your drawing. A V-band clamp suits turbo outlets, downpipes, and other exhaust joints that must come apart for service.
A worm gear clamp, also called a screw clamp, tightens a band with a screw. It is a simple clamp for low-pressure hoses such as drains, water lines, and light-duty automotive hoses. Order it by hose outside diameter and band width.
A spring clamp holds its tension by spring force. For that reason it follows the hose as the hose expands and contracts with temperature. Fitted with spring clamp pliers, it installs quickly on automotive cooling system hoses. For a quote, send the hose size or a sample.
A quick release clamp opens and closes without tools. A joint can therefore be taken apart and put back together in seconds. Because it is easy to clean and maintain, it suits racing cars, laboratories, and food processing areas. Send the ferrule or hose size and the gasket type.
A custom clamp covers the joints a catalogue clamp does not fit, such as a special flange, a saddle, or a strap with a bracket. Send a drawing or a sample to find out whether we can match it. A custom clamp suits machine builders and maintenance teams replacing an obsolete clamp.
The grade you choose depends on the water, the salt, and the cleaning chemistry around the clamp.
304 stainless steel clamps suit indoor machinery, automation, and dry or mildly humid areas. They cost less than 316L. However, 304 is not the right choice for continuous salt spray or chloride-heavy washdown.
316 and 316L stainless steel clamps are made from steel with 2 to 3 percent molybdenum, which gives better chloride pitting resistance than 304. We recommend them for marine engine rooms, outdoor exposure, and process lines cleaned with chloride-based chemicals. Other stainless grades are available on request.
Polishing, passivation, and electropolishing are available when the joint needs a cleaner or smoother surface.
Stainless steel clamps are chosen where zinc-plated clamps would corrode or where a joint must come apart for service. Each use below names the joint and the clamp type that sits there.
A stainless steel V-band clamp joins the turbo outlet to the downpipe, so that section can be unbolted for service. We machine the V-flanges to your drawing.
Stainless steel T-bolt clamps hold the charge-air hose between the turbo and the intercooler, where the wide band spreads the clamping load over the hose.
A 316L stainless steel clamp holds the raw-water and exhaust hoses on a boat engine, where salt spray corrodes carbon steel and 304 over time.
A stainless steel tri-clamp joins two ferrules between the tank outlet and the pump. It opens quickly, so the line can be taken apart for cleaning.
A custom stainless steel clamp or bracket can replace an obsolete clamp on a pump, filter housing, or frame. We make it when we can match your drawing or sample.
Catalogue clamps cover standard hose and pipe sizes. A custom diameter, a special band width, or an unusual flange profile needs a clamp made for it. We make stainless steel clamps to the size of your hose, flange, or ferrule.
That also covers replacements. If a clamp is obsolete or no longer sold, send the old one as a sample and we will match it.
A clamp does not seal a joint by itself. The seal also depends on the hose, the flange, and the gasket the clamp holds. A V-band clamp pulls two matching flanges onto a gasket. A T-bolt clamp squeezes a hose evenly around its circumference.
We machine the V-flange and the clamp hardware to the same drawing, so they fit each other.
We CNC machine the T-bolts, bridges, nuts, and V-flanges for your stainless steel clamps ourselves, so you deal directly with the factory. The dimensions also follow your hose or flange.
Before we cut any metal, we check your salt, washdown, or heat exposure and confirm 304 or 316L. We also ask that the band, bolt, bridge, and nut share one grade. That way no single piece corrodes ahead of the others.
After you send a drawing, a sample, or a photo of the joint, our engineers check the flange profile, the gasket, and the hose size before quoting. Samples are typically ready in about 20 days.
A V-band joint and a tri-clamp joint each depend on a matching product sold on another page.
A stainless steel V-band clamp pulls a matched pair of V-band exhaust flanges together. The clamp and the flange profile are therefore chosen as a set.

| Factor | What to Confirm | Why It Matters |
|---|---|---|
| Connection | A hose over a spigot, a flanged exhaust or pipe joint, or a ferrule joint | The connection decides between a T-bolt, V-band, or tri-clamp. |
| Installed diameter | The outside diameter of the hose over the fitting, or the flange outside diameter | The clamp must close around the installed size, not the free hose size. |
| Band or flange | Band width, V-flange profile, or ferrule size | A V-band clamp must match the flange profile. |
| Hardware | Bolt, nut, bridge, and gasket type | The hardware and the gasket are part of the joint. |
| Grade | 304 or 316L, and any other grade you need | The salt, washdown water, and cleaning chemistry set the grade. |
| Finish | As machined, polished, passivated, or electropolished | A cleaner surface may be needed on process lines. |
| Quantity and sample | Drawing or sample, quantity, prototype or production | We confirm the clamp style from a drawing or sample before quoting. |

The joint decides the type. Use a T-bolt, worm gear, or spring clamp for a hose over a spigot, and a V-band clamp for a flanged exhaust or pipe joint. Use a tri-clamp for a ferrule joint that opens for cleaning. If you are unsure, send a photo or drawing of the joint for us to confirm the style.
A hose clamp squeezes a flexible hose onto a spigot. A V-band clamp, by contrast, pulls two matching flanges together onto a gasket. A V-band clamp therefore has to match the flange profile and diameter, not only the pipe size.
Yes, if the grade is 316 or 316L, because its molybdenum gives better chloride resistance than 304. Use 316L for the band, the bolt, and the nut too, since a lower-grade piece would corrode first.
A worm gear clamp tightens a band with a screw. It suits low-pressure hoses. A T-bolt clamp, by contrast, has a wide band with a bolt and a bridge. This design spreads the clamping load around the hose. It therefore suits charge-air and coolant connections.
Send a drawing or sample. Otherwise, list the clamp type, the hose or pipe diameter, the flange or ferrule type, the grade, and the quantity. We accept DXF, DWG, STEP, IGES, and PDF drawings with dimensions.
Send the clamp type, hose or pipe diameter, flange or ferrule type, grade, and quantity, plus a drawing or sample.
Our engineers review your stainless steel clamp request or drawing. You receive a specific quote within 24 hours.
Standard lead time for stainless steel clamps is 30 days. Custom designs are sampled before the full production run.
We ship stainless steel clamps by sea, air, or express courier. A tracking number follows once the order ships.
We support small-batch and prototype runs with no hard minimum order quantity. A first prototype run is typically around 100 pieces.
Choosing the wrong tri-clamp size can cause leaks and delays. This guide explains sanitary clamp sizing logic, tube OD versus ferrule OD, shared ferrule rules, onsite measurement methods, and common mistakes.
