Parker FB4MES2-HBLK Male Swivel Elbow 1/4 in Od 1/8 in Nptf

Product Description

The PARKER FB4MES2-HBLK is a push-to-connect male swivel elbow tube fitting designed for pneumatic and fluid control plumbing systems. It accepts 1/4 inch OD tubing and connects to a 1/8 inch NPTF male thread. The swivel elbow configuration allows for directional adjustment during installation, reducing stress on tubing runs. Constructed from Kynar (PVDF) with an FKM o-ring, this fitting handles pressures up to 250 psi and maintains a vacuum rating of 28 in-Hg. The black finish aids in system identification. Licensed plumbers, HVAC technicians, and industrial piping contractors install this type of fitting.

This fitting is suited for residential and light commercial pneumatic lines, instrumentation tubing, and chemical-resistant fluid transfer applications where corrosion resistance and a reliable push-to-connect interface are required. Kynar construction makes it appropriate for mildly aggressive media. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant, which is an advantage in high-cycle or vibration-prone installations. Typical use cases include compressed air distribution panels, process control tubing, and HVAC pneumatic control lines.

Compatibility

Designed as an OEM-style push-to-connect fitting for use with 1/4 inch OD tubing and 1/8 inch NPTF threaded ports in pneumatic and fluid control systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician. Depressurize and isolate the line before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and is free of burrs before insertion into the push-to-connect collet. Apply an appropriate thread sealant compatible with NPTF fittings and the system media on the male threads; do not overtighten as Kynar fittings can crack under excessive torque.
