Bringing the Market a Choice...

 

Around the world, customers are choosing BI-LOK® tube fittings as the right alternative in tube fittings.     BI-LOK® tube fittings were developed in response to industry demand for an alternative ultra high quality double ferrule instrumentation grade fitting. ALL BI-LOK® tube fittings are engineered and manufactured to withstand the severest service conditions while providing the ultimate in sealing capabilities and reliability. In varied system services from cryogenic to steam, vacuum to tubing yield pressures, BI-LOK tube fittings provide the necessary leak-tight connection. BI-LOK® tube fittings are manufactured to be totally "interchangeable" with the Swagelok® tube fitting. Piece by piece examination reveals that the two brands are totally component intermixable. The exceptional quality standards of both products assure complete reliability of service when intermixing the component parts.

Advantages Double ferrule swaging action Self alignment No transfer of torque to tubing Dual point integral tubing support ASTM material construction Heat code traceability Corrosion-resistant 316 SS components Universal tubing compatibility Low torque, high purity "silver" thread coating Complete component intermixability Tube support ahead of seal Safety packaging with individually sealed "protection schemes" Complete range of configurations and sizes up to 1" No special assembly tools required Minimum flow restriction Will not weaken tube wall Using geometry rather than torque for proper make-up Availability of special configurations and sizes Compensating seal action to accommodate temperature and pressure variations

Product Info Stainless Steel     BI-LOK® tube fittings consist of a body, nut and ferrules constructed of type 316 stainless steel. Straight bodies are machined from cold finished bar stock material that is in accordance with ASTM A479 and shaped bodies are machined from close grained forging in accordance with ASTM A182. Material is heat code traceable. Brass     BI-LOK® brass bar stock fittings are manufactured from premium grade CA360 brass (ASTM B16) and forging from CA377 (ASTM B124) materials. TUBE SELECTION     The selection of the proper tubing is essential to the per- formance of a tubing system. Consideration should be given to a system's pressure, flow, temperature, and environment when choosing the tubing material, size, and wall thickness. See charts for working pressures and data of tubing by material and size. The following is our suggested tubing ordering information. Tube fittings are designed to be used on similar tube materials (Stainless on stainless, brass on copper, etc.). The use of dissimlar fitting and tube material can lead to an unstable system. Stainless Steel Tubing     Type 304 or 316 stainless tubing should be fully annealed seamless or welded and drawn tubing of STM A269, A213, A249, or equivalent specification. Tubing hardness of Rockwell B-90 or less is recommended. Tubing is to be free of scratches or surface abrasions. See charts for working pressure data. Copper     Seamless or soft annealed tubing of ASTM B-75 specification or equivalent. Also, seamless soft annealed Type K or Type L copper temper O water tube of ASTM B-88 specification or equivalent. Tubing is to be free of scratches or surface abrasions.
