Parker 10FSC8N-316 Compression Tube Connector 3/8-18 Npt

Product Description

The PARKER 10FSC8N-316 is a stainless steel compression tube connector designed to join compression tubing to a female NPT threaded port. It features a 3/8-18 NPT thread size with a compression inlet and FNPT outlet, making it a reliable choice for high-pressure and extreme-temperature fluid and gas line applications. Rated to 6100 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1200 degrees F, this fitting is built for demanding industrial, process, and instrumentation environments. Licensed trades and maintenance technicians install this type of connector where leak-tight tubing connections to threaded ports are required.

This compression-to-FNPT connector is suited for use in process instrumentation, hydraulic, pneumatic, and high-purity fluid systems where stainless steel construction is required for corrosion resistance or compatibility with aggressive media. The 5/8 inch tube outside diameter compression end accommodates standard tubing, and the FNPT end threads directly into female-threaded valves, manifolds, instruments, or panels. Typical applications include refineries, chemical processing plants, HVAC hydronic systems, and industrial plumbing where wide temperature swings or high pressures are present.

Key Features

• Maximum working pressure of 6100 psi for high-pressure system use
• Wide temperature range: -425 degrees F to 1200 degrees F
• Stainless steel construction for corrosion resistance and durability
• Compression x FNPT end connections for tubing-to-threaded-port transitions
• 3/8-18 NPT thread standard for compatibility with standard threaded ports
• 5/8 inch tube outside diameter compression inlet

Compatibility

Designed as an OEM-style replacement or new-installation compression-to-FNPT connector for industrial and process systems requiring a 3/8-18 NPT threaded port connection with a 5/8 inch OD compression tube end.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or instrumentation technician familiar with compression fittings and NPT threaded connections. De-pressurize and isolate the system completely before removing or installing any fittings. NPT threads typically require thread sealant tape or compound applied per system media requirements and applicable codes. Do not over-tighten the compression ferrule, as this can deform the tubing and compromise the seal.
