Compression Tube Fittings By Powertech Industries

Compression Tube Fittings We are engaged in the industry as distributors and exporters of Compression Tube Fittings that were developed to meet the industry demand for an alternative ultra high quality double ferrule instrumentation grade fitting. Our range is appropriately engineered to withstand the severest service conditions while offering the ultimate in sealing capabilities and reliability in varied system services from cryogenic to steam, Vacuum to tubing yield pressures. Compression Tube Fittings are compact in design and has low torque design. Construction and Operation :Our range is fabricated of four precision-machined parts: 1) Body2) Front ferrule3) Back ferrule4) Nut. A leak-tight seal is achieved through the simple action of tightening the nut against the nut body. The geometric rotation of the nut provides the axial thrust required to compress the captivity-held ferrules against the outside diameter (O.D.) of the tubing. The staged swaging action of the ferrules during the compression phase of make-up provides the key to sealing superiority. The front ferrule as it is urged forward against the tapered area of the body is forced inward, thus gripping and subsequently sealing the leading edge tightly on to the tubing. Simultaneously the back ferrule, dove tailing directly behind the front ferrule, swages beneath its trailing edge affording the desired coining action the mechanical connection of tubing and fitting. It is this interaction offer rules that allows to achieve its excellent sealing capabilities under a wide variety of application variables.
