Parker 59P-6 Compression Tube End Cap Acetal 150 Psi

Product Description

The PARKER 59P-6 is an acetal compression tube end cap designed to terminate or seal the open end of a compression tube line. Constructed from acetal resin, this fitting offers resistance to moisture and common fluid media encountered in low-pressure plumbing, instrumentation, and fluid distribution systems. It connects via a standard compression fitting interface, making installation straightforward without the need for solvents or adhesives. The 59P-6 is rated for a maximum working pressure of 150 psi and handles temperatures from 0 degrees F up to 150 degrees F, covering a broad range of typical service conditions.

This end cap is suited for residential and light commercial plumbing, instrumentation tubing, and fluid handling applications where a clean, leak-free tube termination is required. It is commonly installed during system shutdowns, staged installations, or wherever a tube run must be capped pending future connection. Plumbers, instrumentation technicians, and industrial maintenance personnel regularly use this type of fitting in potable water, pneumatic, and general fluid service lines.

Key Features

• Acetal construction provides good chemical resistance and dimensional stability
• Compression fitting end connection requires no solvents, thread sealants, or special tools
• Rated to 150 psi maximum working pressure
• Operating temperature range of 0 degrees F to 150 degrees F
• Compact end cap profile minimizes space requirements at tube termination points

Compatibility

Designed as an OEM-style compression tube end cap compatible with standard compression tube fittings in plumbing, instrumentation, and fluid distribution systems.

Installation Notes

Installation is performed by qualified plumbers or instrumentation technicians in accordance with applicable codes such as the IPC or relevant local plumbing standards. Depressurize and drain the system completely before installing or removing any compression fitting. Hand-tighten the fitting initially, then apply a controlled additional turn with a wrench to achieve a proper compression seal without over-tightening the acetal body. Do not exceed the rated 150 psi working pressure or 150 degrees F temperature limit in service.
