Parker CPI Single Ferrule NPT Male Connector, 3/16 in. Tube OD x 1/8 in. Male NPT, Brass

Small line, tight budget, zero room for a leak. The Parker 3-2 FBZ-B connects 3/16 in. tube straight to a 1/8 in. male NPT port, and the brass body keeps the cost down on air, water and instrument service where stainless is more metal than the job needs.

Brass also machines to a clean thread and seats without galling, which matters when you make up a fitting this small by hand in a panel. The CPI single-ferrule end grips the tube and seals in one motion, so you get a repeatable connection without a flare tool or a torch.

Panel builders and instrument techs pull this size constantly for gauge lines, pilot air and low-pressure sensing legs. Collins-Oliver keeps it on the shelf in Baton Rouge for same-day pickup or nationwide shipping. Call (800) 247-5756.
