Parker CPI Series Union, 1/4 in. Tube OD x 1/4 in. Tube OD, 316 Stainless Steel
Splice a 1/4 in. line and walk away confident. The Parker 4-4 HBZ-SS union joins two 1/4 in. tube runs of equal size using a CPI single-ferrule connection on each end, machined in 316 stainless steel.
You need a union the day a run gets damaged, a skid gets relocated, or a length comes up short and there is no time to pull a new run. It is also the honest way to break a line for maintenance, because the joint is designed to come apart and go back together without losing its seal.
The single-ferrule design keeps the parts count low and the assembly fast, which matters when you are making up fittings in a confined space. Collins-Oliver stocks this union in Baton Rouge. Request a quote or call (800) 247-5756.
