1.1/4″ – 11.5 NPTF Alloy Steel Pressure Plug

Pressure plugs are made to high tolerances and are generally of higher quality than pipe plugs, and almost all have taper threads. Properly made and used, they will seal at pressures to 5000 psi and without a sealing compound (pressure tests are usually at 20,000 psi.) they are often used in hydraulic and pneumatic designs.
