Sigma 811001619 90 Degree Pipe Elbow 1-1/2 in Fnpt 150 Lb

Product Description

The SIGMA 811001619 is a FIG 3101 90-degree pipe elbow rated at 150 lb, constructed from galvanized malleable iron for long-lasting corrosion resistance in threaded piping systems. With a 1-1/2 inch nominal size and female National Pipe Thread (FNPT) connections on both ends, this elbow changes flow direction by 90 degrees in standard threaded pipe runs. It is a standard fitting used by licensed plumbers and pipefitters working on water supply, gas distribution, and general industrial piping where a durable threaded fitting is required.

This fitting is suited for residential and light commercial plumbing, heating, and gas piping systems where 150 lb rated malleable iron fittings are specified. The galvanized finish provides added protection in wet or corrosive environments. It is commonly installed in threaded black or galvanized pipe assemblies following standard building plumbing and mechanical codes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) where applicable. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly.
