SS 304 304L Taper Plug

What is SS 304/304L Taper Plug?

An SS 304/304L Taper Plug is a precision-machined threaded plug designed to permanently or temporarily seal threaded openings in pipes, valves, manifolds, pressure vessels, hydraulic systems and instrumentation equipment. Its tapered thread profile creates a tight mechanical seal that minimizes leakage while providing excellent pressure resistance.

Manufactured using premium-grade Stainless Steel 304 and Stainless Steel 304L, these taper plugs offer exceptional resistance to oxidation, moisture, industrial chemicals and atmospheric corrosion. The low carbon content of SS 304L improves weldability and minimizes carbide precipitation, making it ideal for welded assemblies and corrosive process environments.
