Parker 8MSC4N-316 Compression Tube Connector 1/4-18 Npt

Product Description

The PARKER 8MSC4N-316 is a stainless steel compression tube connector designed to join instrumentation tubing to male NPT pipe threads. It provides a leak-tight mechanical connection using compression-style tube gripping, eliminating the need for soldering or flaring. Rated to 6,300 psi maximum working pressure, this fitting is built for demanding applications in high-pressure fluid and gas systems. At 1.71 inches overall length and weighing just 0.142 pounds, it is compact enough for tight installation spaces. The 316-series stainless steel construction resists corrosion in aggressive media and harsh environments, making it a go-to choice for instrumentation and process piping work.

This connector is suited for use in industrial, commercial, and process control applications where a reliable compression-to-NPT transition is required. Typical installations include instrumentation lines, hydraulic systems, pneumatic tubing runs, and process fluid circuits. It is commonly specified in oil and gas, chemical processing, HVAC instrumentation, and similar trades where stainless steel fittings and rated pressure integrity are required. The compression end accepts standard instrumentation tubing, while the male NPT end threads directly into female-threaded ports, valves, or manifolds.

Key Features

• 6,300 psi maximum working pressure rating for high-pressure service
• Compression x MNPT end connections allow tubing to pipe-thread transitions without soldering or flaring
• 316 stainless steel construction for corrosion resistance in aggressive or wet environments
• 1/4-18 NPT thread size fits standard quarter-inch male NPT ports
• Compact 1.71-inch overall length suits tight installation clearances
• Single-piece package quantity suitable for maintenance and retrofit applications

Compatibility

Designed as an OEM-style compression tube connector for instrumentation and process piping systems using 1/4-18 NPT female-threaded ports and compatible compression-style tubing connections.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians. Depressurize and isolate the line completely before disassembly or fitting installation. Hand-tighten the compression nut onto the tubing, then apply the additional turns specified by the fitting manufacturer for the tubing material being used. Ensure NPT threads are sealed with appropriate thread sealant or tape rated for the media and pressure in service, in accordance with applicable plumbing and process piping codes.
