Inch 304 Stainless Steel and Nylon Plastic: Use with welded 304/304L and 316/316L stainless steel that meets ASTM A269 or ASTM A270, except ASME BPE: Use with welded or seamless 304/304L stainless steel that meets ASTM A269 or ASTM A270
Metric 304 Stainless Steel: Use with welded 304/304L and 316/316L stainless steel
Inch 316 Stainless Steel: Use with welded 304/304L and 316/316L stainless steel
Metric 316 Stainless Steel: Use with welded 316/316L stainless steel

Wing nut—These clamps tighten by hand, no tools required. Clamps with a spring closure can be installed with one hand, as the spring holds the clamp in place. Clamps with a safety wing nut have a wider wing nut base and a narrower clamp gate than our other wing nut clamps, so they stay latched even when bumped and knocked. This is useful in steam lines where accidentally releasing the clamp could cause injuries. They also have a leak-before-burst design, so rather than bursting dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.
Bolt—These clamps handle higher pressures than wing-nut and lever clamps for a stronger, more secure hold. Tighten them with a wrench. Clamps with double-bolt meet ASME design standards for pressure vessels.
Lever—These clamps are best when you need to frequently open and close this connection. They reduce the risk of damage caused by over- or under-tightening the connection because the lever compresses the gasket evenly every time. This also creates a flush connection that minimizes spots where bacteria could grow. A threadless design prevents improper tightening caused by damaged threads. Easy to adjust, these clamps don't require tools to use and can be used with multiple gasket materials.
Recessed nut—These clamps are tamper resistant to reduce the risk of product contamination. A hex socket adapter is required to loosen the nut. They have a leak-before-burst design, so rather than burst dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.
Clamps with a hole for a lockout help you comply with Hazard Analysis and Critical Control Point (HACCP) programs and Good Management Practices (GMP).
Clamps with a two-pin hinge require less clearance to open than other clamps. Use these for installation in tight spaces.
304 stainless steel clamps have very good corrosion resistance. 316 stainless steel clamps are more corrosion resistant than 304 stainless steel clamps. Nylon clamps are lightweight compared to stainless steel clamps.

The temperature rating of the fitting will vary depending on the gasket or O-ring material you choose. Buna-N is oil resistant. EPDM resists water and steam and works well in humid environments. Silicone withstands high temperatures. Fluoroelastomer stands up to fuel, oil, and acid condensates. PTFE withstands harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

Extra-Support High-Polish Metal Quick-Clamp Sanitary Tube Fittings

- For Use With: Dairy, Water
- Temperature Range: -30° to 200° F
- Tubing:
304 Stainless Steel: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
316 Stainless Steel: Use with welded 304/304 L or 316/316L stainless steel - Specifications Met: See table
Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings. They permit easy access to your line. With a smooth finish on the interior, they prevent bacterial growth and help you remove product residue. The pressure rating of the fitting will depend on the clamp you choose.
304 stainless steel fittings have very good corrosion resistance. They’re 3-A certified to meet sanitary design standards. On fittings with a butt-weld end connection, the flanged end of the male adapter interlocks with the flanged end of the female adapter to provide extra support to your line. To assemble, weld the adapters to tubing, then clamp the flanged ends together with a gasket for a strong, leak-tight seal that permits easy access to your line.
Note: To complete a connection, you’ll need a male and female straight adapter, a clamp, and a gasket (all sold separately).
