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. The design of LEVL-SEAL plug permits seating within half a pitch in a normally tapped hole. Conventional plugs have a looser tolerance of a full pitch and usually protrude above the surface. Flush seating improves appearance and adds safety.

  • Precision hex socket with maximum depth for positive wrenching at higher seating torques
  • Used properly they will seal at pressures to 5000 psi and without a sealing compound (pressure tests are usually at 20,000 psi).
  • Flush seating is achieved through closer control of thread forms, sizes and taper-improves safety and appearance
  • Heat treated alloy steel for strength and rounded closely controlled for better sealing
