37° Flared Fittings for Steel Tubing

- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately. Fittings are zinc-plated steel for fair corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.

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.

O-Ring Face Seal Fittings for Steel Tubing

- For Use With: Air, Hydraulic Fluid
- Temperature Range: -30° to 250° F, except BSPP fittings are -20° to 230° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J1453
A tube adapter sits flush against the flat face of the fitting so you can slide the tubing and fitting sideways to disconnect in cramped spaces. Fittings are also known as zero-clearance fittings. To install, weld a tube adapter to the tubing with a brazing ring (sold separately), then mate the tube adapter to the fitting and screw on the nut. As the nut is tightened, the tube adapter compresses the O-ring, creating a strong seal. Fittings are zinc-plated steel for fair corrosion resistance. Nuts and tube adapters are sold separately.

Plastic Push-to-Connect Tube Fittings for Chemicals

- For Use With: Inch: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
Metric: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Sodium Carbonate, Sulfuric Acid - Temperature Range: Inch: 0° to 270° F
Metric: 32° to 175° F - Tubing: Use with hard (Durometer 55D-60D) FEP plastic
Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.
PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.
