316 Stainless Steel Tube Fittings

Stainless Steel 316 Compression Fittings manufacturer in India

Used in plumbing and electrical conduit systems, the SS 316 Tube Compression Fittings are used to join two tubes or two thin-walled pipes together. As a component, the 316 Stainless Steel Compression Tube Fittings permits easy disconnection and reconnection.

ASTM A276 Stainless Steel 316 Hydraulic Fittings and Push To Connect Tube Fittings in many sizes

The SS UNS S31603 Tube Adapter Fittings can be used to change the shape of a piping system based in marine engineering as well. Since these 316 Stainless Steel Tube Fittings are able to resist seawater and brine solutions, the ASTM A276 Stainless Steel 316 Tube Clamp Fittings are used to fix pipe securely in marine environments. Although costlier than alloy grade 304, the ASTM A479 316 SS Air Tube Fittings is used in those applications where the properties of grade 304 prove to be inadequate. For instance, the corrosion resistance properties of Stainless Steel 316 Push To Connect Tube Fittings are much higher than grade 304. In addition, the 316 Stainless Steel Threaded Pipe Fitting is resistant to acids and alkalis as well.

Os-Lok is your superior alternative to Swagelok fittings & Parker A-lok.  Similar to Parker Instrumentation fittings, Os-Lok 316 Stainless Steel Tube Fittings work reliably on both seamless and welded-redrawn, fully annealed SA 213 TP304, SA 213 TP316 and SA 213 TP316L Tubing.
