Challenge

A manufacturer of advanced water jet cutting equipment needed a high-pressure dynamic seal for a piston tasked with intensifying water pressure to a staggering 60,000 psi. The seal had to perform flawlessly in a reciprocating application—where failure wasn’t an option.

Engineered Solution

Marco Rubber & Plastics’s technical team custom-engineered a robust sealing solution tailored for ultra-high-pressure environments. The design featured a special filled PTFE for low friction and wear resistance, energized by a stainless steel spring, and reinforced with a high-performance backup ring system for added durability and pressure stability.

Performance Proven

The custom seal assembly was rigorously tested under real-world conditions. It passed all performance benchmarks—delivering exceptional leakage control, long-term durability, and the reliability demanded by high-precision cutting equipment.
