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).

Nuts for Nickel-Plated Brass Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Lubricants, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -75° to 550° F
- Tubing: Use with copper
- Specifications Met: DIN 3870
Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings. Made of nickel-plated brass, they resist corrosion better than plain brass. All meet DIN 3870, which is an international standard for tube fitting dimensions.

Sleeves for 37° Flared Fittings for Steel Tubing
- For Use With: Air, Fuel Oil, Hydraulic Fluid, Mineral Oil
- Temp. Range: -60° to 400° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°. Sleeves are zinc-plated steel for fair corrosion resistance. They are also known as ferrules.
Inch × metric sleeve adapters convert the fitting from inch to metric.
