Overview
The Bi-Lok P9LOK-316-1 T-Connector is a precision-engineered dual ferrule tube fitting manufactured in 316 stainless steel. BI-Lok Series D Dual Ferrule Tube Fittings are composed of four precision machined component parts: fitting body, front ferrule, back ferrule, and nut, and are shipped fully assembled and individually bagged. Once the tubing has been fully inserted into the fitting, a leak tight seal is achieved through the simple action of tightening the nut against the fitting body. This T-connector provides a secure junction point for three tubing runs, delivering dependable performance in demanding industrial environments.
Key Features
- 316 Stainless Steel Construction: Superior corrosion resistance for chemical and marine applications
- Dual Ferrule Design: The tightening of the nut provides the axial thrust required to engage the captively held ferrules against the outside diameter of the tubing.
- Swagelok Compatible: BI-Lok Series D Dual Ferrule Tube Fittings are manufactured to be completely component intermixable with the Swagelok brand of tube fittings. Independent third party testing concluded that piece by piece intermixing of each manufacturer’s component parts, in various combinations, yielded no performance degradation of the fitting connection.
- Pre-Assembled: Arrives fully assembled and individually packaged, ready for immediate use
- T-Junction Configuration: Enables three-way tubing connections for complex fluid routing
