Threaded Caps and Plugs

Unbrako Pressure Plugs are made to closer tolerances, are generally of higher quality, and almost all have taper threads. The design of LEVL-SEAL plug permits seating within half a pitch in a normally tapped hole; compared to a full pitch with conventional plugs. Flush seating improves appearance and adds safety. Teflon coating acts as a lubricant and a seal. The coating reduces any tendency of the plug to "freeze" as a result of rust or corrosion.<ul><li>PTFE coating material provides a combination of extra hardness and abrasion resistance which permits reuse up to 5 times without appreciable loss of seal.</li><li>Precision hex socket with maximum depth for positive wrenching at higher seating torques </li><li>Flush seating is achieved through closer control of thread forms, sizes and taper-improves safety and appearance</li><li>Controlled chamfer and the PTFE coating, which acts as a lubricant and seal, allow for faster installation. </li></ul>

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.<ul><li>Precision hex socket with maximum depth for positive wrenching at higher seating torques</li><li>Used properly they will seal at pressures to 5000 psi, without a sealing compound (pressure tests are usually at 20,000 psi).</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>
