Made with proprietary Avalon PTFE, Arlon PEEK, and elastomer materials, the new L-Cap seal is said to exceed industry standards for performance and durability, ensuring long service life, minimal fluid leakage, and excellent performance across a broad temperature range.

Used in critical flight actuation systems, Greene Tweed’s L-Cap seal provides superior fluid sealing in hydraulic cylinders under extremely high pressures.

The company’s proprietary Avalon PTFE, Arlon PEEK, and elastomer materials ensure high durability and minimal wear over the lifetime of an aircraft. Greene Tweed’s proprietary materials exceed the low-temperature performance requirements set forth by aviation industry standards without sacrificing high-temperature performance.

The seal also delivers effective leak prevention, exceeding customer requirements for minimising hydraulic fluid leakage. In addition, L-Cap seals are easier to install than other aviation rod seals, thereby reducing actuation system failures upon initial startup.

Greene Tweed’s durable L-Caps function well in single- or dual-seal hydraulic cylinders and are designed to mitigate the pressure trap that can occur in dual-seal systems by enabling pressure relief, all without a complicated or costly seal design.
