Extra-High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- For Use With: Air, Beverage, Dairy, Deionized Water, Food, Pharmaceuticals, Water
- Temperature Range: See Gaskets
- Tubing:
Fittings with 700 psi @ 72° F max. pressure: Use with 316/316L stainless steel that meets ASTM A269 or ASTM A270
Fittings with all other max. pressures: Use with 316/316L stainless steel that meets ASTM A249, ASTM A269, or ASTM A270
Gaskets: Use with 304/304L and 316/316L stainless steel - Specifications Met: See table
- Certification: Material Certificate with Traceable Lot Number and Test Report
Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth. Use them in pharmaceutical and bioprocessing applications. Also known as tri-clamp fittings, they connect with a clamp, a gasket, and another quick-clamp fitting for a fast and easy way to access your line. Fittings are 316 stainless steel for excellent corrosion resistance.
Fittings with barbed hose end connect flexible hose or tubing to your system. Secure with a hose clamp (sold separately).
The pressure rating of the fitting will depend on the clamp you choose.
The temperature rating of the fitting will vary depending on the gasket material you choose.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Gaskets
Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.
