1/4BSPT PRESSURE PLUGS 3/4 TAPER UNBRAKO

Unbrako Pressure Plugs are made to closer tolerances, are generally of higher quality, and almost all have taper threads. When properly used, they seal at pressures to 5000 psi, without a sealing compound (pressure tests are usually at 20,000 psi). They are often used in hydraulic and pneumatic designs. Dryseal plugs are ideal when the plug needs to be reused because more threads are engaged and therefore they resist leakage better. Moreover, they are also preferred in soft metals to reduce over-torquing.
