Female Tube Adapter (Metric Tube to ISO Parallel – RP)

All Categories

Metric Tube to ISO Parallel - RP

The Female Tube Adapter (Metric Tube to ISO Parallel – RP) is a precision-engineered fitting that allows for a secure, leak-proof transition between metric tubing and male ISO parallel (BSPP) threaded components. It features a smooth, unthreaded metric tube stub on one end—designed for integration into a standard double-ferrule compression fitting—while the opposite end provides a female ISO parallel thread with an RP-style sealing face. This configuration typically achieves a pressure-tight seal by seating against a gasket or O-ring at the base of the male thread, ensuring high-pressure integrity without the need for thread sealants.
