Inserts
Knurled, helical and ultrasonic inserts for plastics that hold.
Product Category
Leak-tight connections in BSP, NPT and metric threads.

Fittings are where a thread either seals or it does not. Every Rajhans fitting is cut on calibrated tooling and checked with thread plug and ring gauges, so BSP stays BSP and NPT stays NPT — lot after lot.
The range covers compression and flare fittings, hose barbs and nipples, plugs, elbows, tees and unions for plumbing, gas, pneumatic and instrumentation lines, in natural or plated finish.
