Valves & Compression Tube Fittings
'MASS' tube fittings were developed in response to industry demand for an alternative ultra high quality double ferrule instrumentation grade fitting. All 'MASS1 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. 'MASS' make single and double compression tube fittings provides leak proof joints at all tubing connection, this eliminates leakage. 'MASS' Needle valve is made from single piece forged body or bar stock construction. 'MASS' instrument Ball valves is very compact and low torque design.

Our Capabilities :

With a rapidly expanding manufacturing facility at Chhatral near Ahmedabad (Gujarat) and a comprehensive network of marketing and distribution outlets across the globe. The company is able to offer outstanding support to our customers worldwide
Construction and Operation :
'MASS' tube fittings are composed of four precision-machined parts: 1) Body, 2) Front ferrule, 3) Back ferrule, 4) 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.
