Instrumentation Pipe Fittings — 316 Stainless Steel

About Pipe Adapters, Bushings, Plugs and Caps

This group handles thread conversion, size reduction and blanking in threaded instrumentation pipework. A pipe adapter changes one thread form or gender to another, for example a male NPT to a female BSPP, so equipment built to different standards can be connected. A reducing adapter changes size as well as thread. A reducing bushing is a compact alternative: it screws into a larger female port and presents a smaller female thread, which keeps the assembly short.

For closing off ports there are hex plugs, hollow hex plugs and pipe caps. A hex plug screws into a female port and is tightened with a spanner. A hollow hex plug is driven with a hex key, so it can sit lower in the port where clearance is tight. A pipe cap fits over a male thread to seal the end of a nipple or pipe.

All parts are SS316, with sizes from 1/16" to 2" and threads in NPT, BSPT, BSPP, metric and SAE/MS forms. Typical uses include instrumentation, chemical and power generation plant.

• Tapered threads (NPT, BSPT) seal on the thread; parallel threads (BSPP, metric, SAE/MS) need a washer or O-ring.
• Check end 1 and end 2 size, thread and gender separately.
• Filter by fitting type, thread and size, then request a quote from the UK team.
