Compression Fittings

Get a secure seal at higher pressuresCompression fittings are an excellent choice to connect rigid tubing systems and withstand higher pressures than barbed fittings. Assemble the fitting to the tubing by sliding the tubing through a sealing ferrule and using the nut to compress down to form a secure seal.

Brass. Good chemical resistance; rated to 400 psi. Temp range: –85 to 482°F (–65 to 250°C). Include brass ferrules; UL-listed for use with flammable liquids; meet ASA, ASME, and SAE (J512) standards.

Nylon. Good chemical resistance. Temp range: –50 to 250°F (–46 to 121°C). Sterilize by ethylene oxide only.

PFA. Superior chemical resistance; rated to 150 psi (40 psi without grooving tool). Temp range: up to 347°F (175°C). Include built-in ferrules. Sterilize by either ethylene oxide or autoclave.

Polypropylene (PP). Very good chemical resistance.

Black: Rated to 300 psi. Temp range: 0 to 212°F (–17 to 100°C). With SS gripping rings. Sterilize by autoclave.

White: Rated to 220 psi. Temp range: 32 to 212°F (0 to 100°C). With plastic grippers. Sterilize by ethylene oxide.

PVDF. Excellent chemical resistance; rated to 220 psi. Temp range: –20 to 275°F (–29 to 135°C). Include plastic grippers. Sterilize by ethylene oxide or autoclave.

Stainless steel (316 SS). Very good chemical resistance; pressure limit depends on the tubing used, not the fitting. Temp range: –40 to 200°F (–40 to 93°C). Include ferrules. Sterilize by either ethylene oxide, autoclave, or gamma irradiation.

Note: Pressure ratings given are for smaller tubing ODs at 77°F (25°C). Ratings decrease with increases in tubing OD or temperature.
