Parker 4FSC2N-316 Compression Tube Connector 1/4 Od Fnpt

Product Description

The PARKER 4FSC2N-316 is a stainless steel compression tube connector designed to join 1/4-inch OD tubing to a 1/8-27 NPT female pipe thread port. The fitting transitions from a compression-style tube grip on one end to an FNPT connection on the other, providing a reliable, leak-resistant seal in high-pressure and extreme-temperature fluid or gas systems. Rated to 10,300 psi maximum working pressure with a temperature range from -425 degrees F to 1200 degrees F, this connector is built for demanding instrumentation, process, and industrial service applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This connector is suited for use in instrumentation tubing runs, pneumatic and hydraulic control lines, chemical process piping, and high-purity fluid systems where stainless steel corrosion resistance is required. The compression-by-FNPT end configuration makes it a practical choice when connecting small-diameter tubing to threaded ports on valves, manifolds, gauges, or panel fittings. Its compact overall length of 1.23 inches allows installation in tight panel or rack spaces where clearance is limited.

Key Features

• 10,300 psi maximum working pressure rating for high-pressure service
• Stainless steel construction provides corrosion resistance in aggressive media environments
• Wide temperature range: -425 degrees F to 1200 degrees F
• Compression x FNPT end connections for tube-to-pipe-thread transitions
• 1/4-inch tube OD compression end with 1/8-27 NPT female thread
• Compact overall length of 1.23 inches for space-constrained installations

Compatibility

Designed as an OEM-style compression fitting for use with 1/4-inch OD tubing and 1/8-27 NPT threaded ports in instrumentation and process piping systems.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician in accordance with applicable codes including ASME B31.1 or B31.3 for pressure piping systems. Depressurize and isolate the line completely before removing or installing any compression fitting. Do not over-tighten the compression nut, as this can deform the ferrule and compromise the seal. Verify that the tubing OD and wall thickness are compatible with the fitting before assembly.
