Product Overview
Swagelok SS-4P4T is a quarter-turn plug valve from the P Series instrumentation valve line. It uses a PTFE-coated 316 stainless steel cylindrical plug to control flow with a simple 90-degree handle rotation. Rated to 3000 PSIG with 1/4 in. female NPT connections on both inlet and outlet. Suited for manual shutoff in gas, liquid, and chemical service lines where a compact, low-profile valve is needed.

Frequently Asked Questions
Will this connect directly to 1/4 in. Swagelok tube fittings?
No. This valve uses 1/4 in. Female NPT threads. A Swagelok NPT-to-tube adapter (such as the SS-400-7-4) is required to connect to 1/4 in. compression tube fittings.
Is this valve function tested?
Valve action is smooth and threads check out fine upon visual inspection. Pressure or leak testing was not performed. Verify suitability for your application before installation.
What is the difference between this and the SS-4P4T-BK or SS-4P4T-RD variants?
The SS-4P4T-BK has a black handle and the SS-4P4T-RD has a red handle, commonly used to identify emergency shutoffs or specific chemical service. This unit is the standard SS-4P4T with no colored handle designation.
Can this valve be used for throttling, or is it shutoff only?
The SS-4P4T can throttle flow but is primarily designed as a shutoff valve. For precision flow control, a needle valve is the better choice.
Sourced from a government research facility and confirmed with smooth valve action. Verify NPT thread compatibility with your existing fittings before ordering.
