The BHO product series is a single-acting piston seal featuring a FlexiSeal® design with a helicoil spring. It stands out due to its extreme temperature and chemical resistance and is ideal for higher-pressure applications.

• Extended heel that reduces effects of extrusion.
• Heavy dynamic lip (outside) ensures longest life.
• Short, wiper-type dynamic lip reduces frictional forces due to hydrostatic pressure.
• Helical spring for high load and small deflection range.
• Squared, long static lip stabilizes the seal.
• Widest range of cross-sections and diameters available, including sizes for upgrading standard O-ring grooves.
• Many high-resilience energizer options available, including choice of light, medium and heavy loads and NACE for oil field use.
• Low-cost elastomeric energizers available, all with excellent fatigue resistance.

Range of application:
For high-pressure applications in reciprocating pistons.
