CPF Pressure Fittings

Brand: Crystal Engineering by Ametek

CPF Fittings and Hose are a new line of quick-test pressure fittings for calibration and test applications -- designed with an emphasis on safety.

Crystal Pressure Fittings (CPF) perform up to 15 000 psi / 1000 bar, and feature a safety weep hole to alert you before you accidentally disconnect from a pressurized system. It can also be used as a bleed point.

Each fitting is machined in 316 Stainless Steel and laser markings indicate the fitting type, size, part number, and Maximum Allowable Working Pressure to prevent a mismatched connection.

An industry-first patented O-ring connection allows CPF Fittings to maintain a leak-free seal up to 10 000 psi with only finger-tightening.

This offers an alternative to commonly-used NPT Fittings, which require technicians to wrap their fittings in thread tape and use a wrench to tighten each installation.

Unlike other quick-change fittings, the O-rings in CPF Fittings are also easily replaceable.

New! We have added a new line of BSP fittings, including the industry's first 1000 bar finger-tight fitting.
