RT RP – Restrictors Flow Limiters

RT/RP Threaded flow restrictors limiters

Metric, UN, NPTF or on request threads.
The standard material is stainless steel AISI303 or copper – The diameter of the passage is on customer request.
Threaded models can be easily replaced to adjust flow to customer calibration needs.
Special models available on request.
