Threads :

Threads utilized on Wesmec Instrument Pipe Fittings are National Pipe Taper (NPT ) which exceed the requirements of ANSI B1.20.1

Pressure Rating :

Pressure Ratings for temperatures up to 100o F are identified for each individual pipe fitting in the dimensional data charts.

Temperature :

Temperatures noted below apply to basic fitting capabilities. In all cases consideration must also be given to the type of thread sealant used. For example, teflon tape has a maximum temperature rating of 450o F. 316 Stainless Steel : -325o F to 1200 o F ( – 198oC to 648o C ) Brass : -325oF to 400o F ( -198o C to 204o C ).

Materials :

Wesmec Instrument Pipe Fittings are available as standard in Brass and 316 Stainless Steel. The current price list indicates those items that are available as standard. Wesmec Pipe Fittings can also be supplied in other materials including Monel, Hastelloy C, Inconel and Titanium, and in special shapes. Contact your local Wesmec distributor for further information.
