Stainless Steel SMC 8-4N | 1/2 in. Tube OD x 1/4 in. MNPT Male Connector – Bored-Through

The SMC 8-4N is a 1/2" Tube OD x 1/4" Male NPT connector built for high-integrity performance in demanding fluid and gas systems. Machined from corrosion-resistant 316 stainless steel, this straight fitting features a bored-through internal body, enabling full-flow transfer—ideal for drain, purge, or sampling lines where unrestricted media movement is required.

Its compact form factor and dual-ferrule compression end provide a leak-tight seal in clean-in-place (CIP) instrumentation, sanitary systems, and high-pressure applications. The NPT thread is cut to ANSI standards for consistent installation in process ports and control hardware.

Compatible with Swagelok® style systems, the SMC 8-4N delivers durability, reliability, and high-purity performance where flow control and system cleanliness matter most.

Key Benefits
