Parker 8 Pntx-ss Stainless Steel Flared Tube Plug 1/2 in

Product Description

The PARKER 8 PNTX-SS is a stainless steel flared tube plug designed to cap off 1/2 inch OD tubing with a 37-degree flare connection. It provides a secure, leak-tight seal in hydraulic, pneumatic, and fluid transfer lines where a port or tube end must be closed off during service, testing, or system reconfiguration. Rated to a maximum working pressure of 7,200 psi and a temperature range of -425 degrees F to 1,200 degrees F, this plug handles demanding environments where carbon steel or brass fittings are not suitable. Licensed plumbers, pipefitters, and hydraulic technicians install this fitting in industrial and commercial applications.

This tube plug is suited for use in high-pressure hydraulic systems, refrigeration lines, fuel systems, and instrumentation tubing where stainless steel construction is required for corrosion resistance or elevated temperature service. The 37-degree flare end connection conforms to SAE J514 and ISO 8434-2 standards, making it compatible with standard JIC-style flare fittings found throughout industrial fluid power and process piping systems. It is a single-piece component installed with standard flare fitting wrenches and requires no sealant when properly torqued to the mating fitting.

Key Features

• Stainless steel construction for corrosion resistance in aggressive media and elevated temperature environments
• 37-degree flare end connection per SAE J514 and ISO 8434-2 for compatibility with standard JIC flare fittings
• Maximum working pressure of 7,200 psi for high-pressure hydraulic and fluid power applications
• Wide temperature range from -425 degrees F to 1,200 degrees F for use in cryogenic through high-heat service
• Compact overall length of 0.94 inches for installation in space-constrained tubing assemblies
• Single-piece plug design with no internal components to fail or require maintenance

Compatibility

Designed as an OEM-style replacement or service fitting for 1/2 inch OD tubing systems using 37-degree flare connections per SAE J514 and ISO 8434-2 standards in hydraulic, pneumatic, and fluid transfer applications.

Installation Notes

Installation is performed by licensed pipefitters, hydraulic technicians, or qualified tradespeople following applicable fluid power and piping codes. De-pressurize and isolate the system completely before removing any fittings or installing this plug. Use appropriate flare fitting wrenches and follow SAE J514 assembly guidelines for proper seating of the 37-degree flare interface. Do not over-torque; the metal-to-metal flare seat does not require thread sealant when mated to a clean, undamaged flare fitting seat.
