Parker 600-0115-1/4 Fastener Seal 1/4 Pipe Thread

Product Description

The PARKER 600-0115-1/4 is a fastener seal designed to provide a reliable, pressure-resistant barrier at threaded fastener and pipe connection points. With an inner diameter of 0.24 inches, an outer diameter of 0.505 inches, and a seal thickness of 0.05 inches, this part seats precisely around 1/4 pipe thread fittings to prevent fluid or gas leakage. It is rated for a maximum operating pressure of 5100 psi and handles a temperature range of -65 to 225 degrees F, making it suitable for demanding service environments. Licensed trades including HVAC technicians, plumbers, and pipefitters install this seal during fitting assembly or repair work.

This fastener seal is used wherever 1/4 pipe thread connections require a sealing element to maintain pressure integrity. Common applications include hydraulic lines, pneumatic fittings, refrigerant circuit connections, and plumbing assemblies where thread-face sealing is required. Its compact geometry fits standard 1/4 pipe thread fastener configurations and is sold individually, making it a practical replacement or service part for single-connection repairs. It is appropriate for both residential and light commercial installations across HVAC, plumbing, and fluid-handling systems.

Key Features

• Rated to 5100 psi maximum operating pressure for high-demand service
• Wide temperature range of -65 to 225 degrees F suits both low-temp and elevated-heat environments
• Precise 0.24 inches ID and 0.505 inches OD dimensions for accurate 1/4 pipe thread fitment
• 0.05 inches seal thickness provides consistent face-sealing compression
• Sold as an individual unit, ideal for targeted single-connection service work

Compatibility

Designed as an OEM-style replacement fastener seal for 1/4 pipe thread connections in hydraulic, pneumatic, refrigerant, and plumbing systems requiring face-sealing at threaded fastener points.

Installation Notes

This seal is typically installed by licensed plumbers, HVAC technicians, or pipefitters during fitting assembly or scheduled maintenance. Before servicing any pressurized line, relieve all system pressure and isolate the section being worked on according to applicable codes such as the IPC or IFGC. Ensure mating surfaces are clean and free of debris before seating the seal to achieve proper compression and prevent bypass leakage. Do not over-torque the fastener, as this can deform the seal and compromise the pressure rating.
