Parker 1 1/2 Gg-s Pipe Coupling 1-1/2 in Fnptf 2000 Psi

Product Description

The PARKER 1 1/2 GG-S is a straight industrial pipe coupling designed for high-pressure fluid and gas line connections in commercial and industrial piping systems. It features female-to-female FNPTF (Female National Pipe Tapered Fuel) threading on both ends at 1-1/2 inches, with a maximum working pressure rating of 2,000 psi. The straight configuration makes it a direct in-line connector for joining two threaded pipe sections. This coupling is installed by licensed plumbers, pipefitters, and industrial maintenance technicians working on pressurized fluid transfer, compressed air, hydraulic, or fuel distribution systems.

This coupling is suited for industrial and commercial installations where a reliable FNPTF threaded connection is required at 1-1/2 inch pipe size. It is appropriate for applications involving high-pressure lines including compressed air distribution, fuel lines, hydraulic systems, and general fluid transfer. The straight fitting shape allows direct in-line joining of two pipe ends without directional change, making it a standard component in pressurized piping assemblies across manufacturing, processing, and mechanical contracting environments.

Key Features

• 2,000 psi maximum working pressure for demanding industrial service
• FNPTF female thread on both ends ensures a secure, tapered fuel-service-rated connection
• 1-1/2 inch thread size accommodates standard industrial pipe sizing
• Straight coupling shape provides direct in-line pipe joining with no directional offset
• 2-3/8 inch hex size allows installation with standard open-end or adjustable wrenches
• Compact overall length of 1-15/16 inches suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems requiring 1-1/2 inch FNPTF straight couplings rated to 2,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or applicable ANSI/ASME B31 piping standards. Depressurize and isolate the line completely before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before making up the joint. Do not over-tighten; follow standard hand-tight-plus-turns practice for tapered NPT fittings to avoid thread damage.
