Parker 66PLPBH-4M-4G Female Bulkhead Tube Fitting Bspp

Product Description

The PARKER 66PLPBH-4M-4G is a push-to-connect female bulkhead tube fitting designed for straight, inline tube-through-panel connections. Constructed from nickel-plated brass with a silicone-free grease lubricant and a UL94 V-0 rated release button assembly, this fitting handles working pressures up to 300 psi across a temperature range of 0 degrees F to 200 degrees F. The 4 mm outside diameter tube connection mates with a BSPP female thread. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting in compressed air, instrumentation, and fluid handling lines where a panel-mount pass-through is required.

This fitting is suited for residential and commercial pneumatic and fluid control systems that require a secure, tool-free tube insertion through a bulkhead or panel wall. The straight configuration keeps the run inline without redirecting flow. The BSPP thread type makes this fitting appropriate for metric-standard plumbing and pneumatic assemblies common in imported equipment and international-specification systems. The silver nickel-plated brass body resists corrosion in light-duty fluid and compressed air service environments.

Compatibility

Designed for use with 4 mm outside diameter tubing in pneumatic and fluid control systems requiring a BSPP female bulkhead connection. Confirm thread type and tube OD before installation.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or pneumatic systems technician. Depressurize the system completely and relieve all fluid pressure before removing or installing any fitting. Verify that the tubing outside diameter is exactly 4 mm and that the mating thread is BSPP before assembly. Do not overtighten the panel locknut — hand-tighten and confirm the tube locks securely by pulling back firmly before returning the system to service.
