Parker 59CA-8 Compression Tube Plug Brass 750 Psi

Product Description

The PARKER 59CA-8 is a brass compression tube plug designed to seal the open end of a compression fitting or tubing line. It installs where a tubing run must be capped off permanently or temporarily during system service, testing, or staged installation. The fitting is rated to 750 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and pneumatic systems. Licensed plumbers, HVAC technicians, and industrial pipe fitters are the primary installers of this type of fitting.

This compression plug is appropriate for use in residential and commercial plumbing, HVAC refrigerant piping (where compatible), pneumatic control lines, and light industrial fluid systems that operate within the rated pressure and temperature envelope. Its brass construction makes it well suited for water, air, and many hydraulic fluid applications. It is sold individually as a single-piece package.

Key Features

• Brass construction for corrosion resistance and reliable sealing in fluid and air systems
• 750 psi maximum working pressure rating for demanding service conditions
• Wide temperature range: -65 degrees F to 250 degrees F
• Compression-style fitting — no soldering or threading required for installation
• Single-piece package quantity for per-unit purchasing flexibility

Compatibility

Designed as an OEM-style compression tube plug for use in systems that accept standard compression-style fittings operating within the rated pressure and temperature limits of this part.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and isolate the tubing line completely before removing any existing fitting or installing this plug. Hand-tighten the compression nut first, then use an appropriately sized wrench to seat the ferrule — do not overtighten. Verify system pressure is within the 750 psi rating before returning the line to service.
