Tight-Seal Plastic Barbed Tube Fittings for Air and Water
Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections. Fittings are nylon for excellent impact and abrasion resistance.
For technical drawings and 3-D models, click on a part number.
- Temperature Range: See table
- Tubing: Use with firm (Durometer 75A-80A) polyurethane rubber or PVC plastic
- Clarity: Black: Opaque; White: Semi-Clear
37° Flared Fittings for Stainless Steel Tubing
- Tubing: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Specifications Met: ISO 8434, SAE J514, except fittings with BSPP and BSPT threads meet SAE J514 only
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They are 316 stainless steel for excellent corrosion resistance. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
For technical drawings and 3-D models, click on a part number.
- For Use With: Air, Hydraulic Fluid, Isopropyl Alcohol, Natural Gas, Phosphoric Acid, Water
- Temperature Range: -420° to 1,200° F
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.

Compression Fittings for Stainless Steel Tubing
- For Use With:
303 Stainless Steel, 316 Stainless Steel with 17-4 PH Stainless Steel Sleeve, and 360 Brass: Air, Water, Hydraulic Fluid
316 Stainless Steel: Air, Cutting Oil, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Mineral Oil, Natural Gas, Steam, Water - Temperature Range: See table
- Tubing:
303 Stainless Steel and 360 Brass: Use with welded or seamless 304 or 316 stainless steel
316 Stainless Steel: Use with seamless 304 or 316/316L/316Ti stainless steel that meets DIN EN 10216-5 or DIN EN 10305-1
316 Stainless Steel with 17-4 PH Stainless Steel Sleeve: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A269 - Specifications Met:
316 Stainless Steel: ISO 8434, DIN 2353
316 Stainless Steel with 17-4 PH Stainless Steel Sleeve: SAE J514
A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings or bite fittings.
316 stainless steel fittings have excellent corrosion resistance.
