Ametek Crystal CPF Pressure Fittings

2026-02-27

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.
