Tylok QC Series Quick Connect Stem - CBC-Lok Port (Valved)
These Valved Tylok QC Quick Connect Stems with CBC-Lok Tube Fitting Ends are available in 1/4" or 3/8" body sizing with 1/8", 1/4", or 3/8" ports for a wide variety of applications. Valved stems give you the full security of a double end shut off (DESO) connection that prevents spillage from both the body and plug side of the quick connect. These quick connects feature 316 stainless steel machined parts, springs, and retaining rings. Featuring a dependable poppet valve and redundant Viton® (FKM) o-ring seals to provide a quick, leak tight seal in both vacuum and pressure systems. A positive valve stop prevents flow checking into the quick connect and a set of guides improve the reliability of the seal. A smooth entrance and positive engagement is insured by Teflon® (PTFE) bonded locking "dogs".
