Parker 1MSC4N-316 Compression Tube Connector 1/4-18 Npt

Product Description

The PARKER 1MSC4N-316 is a stainless steel compression tube connector designed to join tubing to a male NPT threaded port. It features a compression end on one side and a 1/4-18 MNPT end on the other, making it suitable for plumbing, instrumentation, and fluid-handling systems where a reliable, leak-tight connection is required. Rated for a maximum working pressure of 16800 psi and a temperature range of -425 degrees F to 1200 degrees F, this fitting handles demanding service conditions. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this type of connector.

This connector is well suited for high-pressure instrumentation lines, hydraulic systems, and industrial fluid transfer applications where stainless steel is specified for corrosion resistance or extreme temperature service. The compression-by-MNPT configuration allows direct connection of tubing to a threaded port without additional adapters. It is appropriate for both residential and commercial installations where NPT-threaded connections and compression fittings are the standard interface.

Key Features

• 1/4-18 NPT thread size with compression x MNPT end connections
• 316 stainless steel construction for corrosion resistance in aggressive media
• Maximum working pressure of 16800 psi for high-pressure service
• Operating temperature range from -425 degrees F to 1200 degrees F
• Compact single-piece connector — no additional adapters required

Compatibility

Designed as an OEM-style replacement or direct-installation compression tube connector for systems using 1/4-18 NPT threaded ports and compatible compression tubing.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician in accordance with applicable codes such as the IPC or relevant ASME standards. Depressurize and isolate the system completely before removing any existing fittings or installing this connector. Use appropriate tube preparation tools to ensure a clean, square tubing cut for proper compression-sleeve seating. Do not overtighten the compression nut, as this can damage the ferrule and compromise the seal.
