A metal fitting boss seal

Metal Boss Seals
Special Design Metal Seals for AS5202 Fittings

This special design seal is known as a metal boss seal and is our solution for the hydraulic standard AS5202 from SAE. With the best leakage rate, it is an excellent solution for replacing an elastomer O-ring that fails due to the system's conditions. Here are several technology advantages:

  1. Ease of installation: Unlike machined K-Seals that require precision machining and assembly, our integrated seal design can be installed quickly and easily without any special tools or equipment. Aerospace manufacturers save time and money during the assembly process.
     
  2. Lighter weight: Omniseal Solutions' metal boss seal is significantly lighter than its machined competitor – a major technology advantage in aerospace applications where weight is critical. Made from high-strength formed materials, the metal seal reduces overall weight and improves fuel efficiency.

We also offer two different metal boss seal designs for the AS5202 fittings in order to precision match as many hardware and application requirements you need:

  1. You can install directly on the port thread and symmetrical design.
  2. You can locate easily on the tube part of the fitting jacket thanks to the tail of the jacket.
