Value Collection SS-MC-FT4-MN4 Compression Male Connector

Product Description

The VALUE COLLECTION SS-MC-FT4-MN4 is a stainless steel compression tube male connector designed to join a 1/4-inch OD compression tube to a 1/4-inch male NPT threaded port. Constructed from 316 stainless steel, this fitting meets ASTM A276, ASTM A479, and ASTM A182 standards, making it suitable for demanding fluid and gas line applications where corrosion resistance is required. With an overall length of 1.49 inches, it provides a compact inline connection. The compression end creates a leak-tight seal on the tube without threading, while the MNPT end threads directly into a female NPT port. Licensed plumbers and pipefitters typically install these fittings in instrumentation and process piping systems.

This connector is used in residential and commercial plumbing, HVAC refrigerant instrumentation lines, compressed air systems, and process piping where stainless steel corrosion resistance is required. The compression-by-male-NPT configuration makes it well suited for connecting tubing runs to valves, gauges, manifolds, or other threaded components. It is commonly specified in installations that require compliance with ASTM or DIN material standards for tubing fittings.

Key Features

• 316 stainless steel construction for excellent corrosion resistance in wet and chemical environments
• Compression x MNPT end connections for tool-friendly tube-to-threaded-port transitions
• Fits 1/4-inch OD tubing with 1/4-inch male NPT thread on the opposite end
• Overall length of 1.49 inches for compact inline installations
• Meets ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, and DIN EN10272 standards
• NPT thread standard for compatibility with standard North American pipe thread fittings

Compatibility

Designed as an OEM-style compression tube male connector for use with 1/4-inch OD tubing and 1/4-inch female NPT threaded ports in plumbing, HVAC instrumentation, and process piping applications. Referenced equivalent to Swagelok part number SS-400-1-4.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or process piping codes. Depressurize and isolate the line before disassembly or installation. Tighten the compression nut to the manufacturer-specified method for compression fittings — do not overtighten, as this can deform the ferrule and compromise the seal. Apply appropriate thread sealant or PTFE tape to the MNPT threads before making up the joint.
