Crystal CPF Fittings and Hoses are specifically engineered for calibration and test applications - designed with an emphasis on safety. They 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, which 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 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 thread tape and a wrench to tighten each installation. Unlike other quick-change fittings, the O-rings in CPF Fittings are also easily replaceable.
