BI-Lok Tube Fittings

Bi-Lok Series D Dual Ferrule Stainless Steel Tube Fittings offer superior corrosion resistance by utilizing the Internationally patented Nv Pionite Surface Treatment Technology. This innovative surface hardening treatment yields a stable austenite structure layer while maintaining corrosion resistance. Only the leading edge of the rear ferrule is treated. Although this requires additional steps in the manufacturing process, the result is consistent low make up torque without the need to reduce the mass of the rear ferrule.

Interchangeable & Intermixable

Bi-Lok Series D Dual Ferrule Tube Fittings are not only interchangeable, but are component by component intermixable with other popular brands of like design dual ferrule tube fittings. Independent third party testing and years of field experience conclude that piece by piece intermixing in various combinations yielded no performance degradation.
