Ihara Science BI-LOK Tube Fittings

Ihara Science BI-Lok® double ferrule tube fittings provide leak free seals in process, power, and instrumentation applications and are fully heat-code traceable, self-aligning, easy to install and individually packaged in sealed protection pouches. Including superior corrosion and vibration resistant designs, from cryogenic to steam, vacuum to tubing yield pressures, BI-Lok® fittings offer multiple leak free remakes in a wide range of varying pressure and temperature operating environments.

*Stainless products are RoHS compliant.

Construction and Operation

BI-Lok® Double Ferrule Tube Fittings are composed of four precision machined component parts: 1) fitting body, 2) front fer- rule, 3) back ferrule, 4) nut. BI-Lok® Tube Fittings 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. The tightening of the nut provides the axial
thrust required to engage the captively held ferrules against the outside diameter of the tubing. The staged swaging action of the ferrules, with minimal torque transfer to the tubing during make-up, provides the key to BI-Lok’s high integrity sealing capability and exceptional service life.

Quality Control

BI-Lok® Tube Fittings are designed, manufactured and inspected to the rigid quality requirements of our ISO certified production facility. All Stainless Steel Fittings are Heat/Lot code traceable. BI-Lok® Tube Fittings have been tested and certified to a variety of Global International Industry standards and regulatory agencies.

Pressure Ratings

The BI-Lok® Double Ferrule Tube Fitting consists of four elements – nut, front ferrule, back ferrule and fitting body. However, the actual sealing function is accomplished with the addition of a fifth element, the tubing itself. Therefore, the pressure rating of the fitting assembly is a direct function of the tubing select- ed. Proper tube selection is critical and the ultimate responsibility of the system designer/user. The tables listed on page 2 provide the allowable pressure ratings of a variety of commonly used tube sizes and materials.
