Our expertise in base metals, custom coatings, specialty metals, designing for unique envelopes, improved safety, error-proof placement and installation only begins to describe the wealth of engineering, validation and manufacturing solutions we provide customers.
Parker's standard product offering and custom engineered solutions include:
- Metal Seal Size Range: From 0.350" to 60" diameter full hoop; Larger if segmented; Smaller depending on cross-section
- Temperature Range: Cryogenic to 1450°F
- Pressure Range: Vacuum to 50,000+ psi
- Wide range of materials to ensure compatibility with wide range of fluids
- Corrosion resistant material and durable designs to ensure seals will outlast hardware
- Pre-compression features that help overcome installation challenges
- TriCom® coating that extends life by creating an anti-wear and oxidation-resistant system
Platings and Coatings
Platings and coatings create a ductile, low hardness outer surface layer that ensures optimum sealing despite mating surface imperfection.
Coatings such as TriCom® and TriCom-HT™, are electro-deposited coatings that create an anti-wear and oxidation resistant system that significantly reduces seal and mating surface wear caused by thermal expansion and vibrational movement.
The graph above shows typical ranges of leakage rates that may be expected with various types of seals. The widths of the horizontal bars indicate the spread of leakage values that may be expected depending on the specific plating selection and surface condition.
