Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser. To install them, slide off a set and place it on your tubing. Each front sleeve, back sleeve, and nut is made of 316 stainless steel for excellent corrosion resistance. Five sets of sleeves and nuts come on each dispenser. Sleeves are also known as ferrules.

High-Polish Gasket Fittings for Stainless Steel Tubing

- For Use With: Air, Dairy, Water
- Temperature Range: See Gaskets
- Tubing:
Inch Butt-Weld Fittings and Quick-Clamp Fittings: Use with welded 304/304L or 316/316L stainless steel that meets ASTM 269 or ASTM 27
Metric Butt-Weld Fittings: Use with welded or seamless 316 stainless steel - Specifications Met:
304 Stainless Steel Adapters, Caps, and Nuts: 3-A Certified 63-04
Gaskets: See table
Join these fittings with a threaded nut and a gasket for a secure connection that grants you easy access to your line. Also known as bevel seat fittings, the fittings are beveled to fit snugly around the gasket, creating a vibration-resistant seal. Fittings are polished to a smooth finish on the interior to prevent product buildup and bacterial growth.
316 stainless steel fittings have excellent corrosion resistance.
Note: For a complete connection, you’ll need a threaded straight adapter, an unthreaded straight adapter, a gasket, and a nut (all sold separately unless noted).
