Threaded Caps and Plugs

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.<ul><li>Precision hex socket with maximum depth for positive wrenching at higher seating torques</li><li>Precision thread for positive seal, without a sealing compound</li><li>Flush seating is achieved through closer control of thread forms, sizes and taper-improves safety and appearance</li><li>Heat treated alloy steel for strength and rounded closely controlled for better sealing</li></ul>
