Product overview
Structure and Connection
This shouldered sanitary hose adapter integrates a 3A Tri-Clamp flange on one end and a multi-ribbed stepped hose-barb tail on the other, separated by a machined annular retention shoulder behind the clamp neck.
The raised shoulder acts as a positive axial stop for the flexible hose end and provides a collar seat for crimp ferrules or heavy-duty hose clamps in hygienic transfer assemblies.
