Applications with a variable axial gap or other limitations to axial sealing rely on radial sealing solutions. Common sealing technologies require machining grooves into tubes and assembling seals onto both ends. Limitations of this technology include seals rolling and/or pinching, misassembled seals and limited misalignment capability. Another technology for sealing misaligned ports is a flexible hose. While this seals high radial misalignment, it requires clamping onto two pipes and can burst at higher pressures. These limitations lead to leaks, re-work and warranty claims.
Parker's Tube Seals are over molded to a rigid insert creating a one piece sealing solution. This insert enables the Tube Seal to withstand much higher pressures than traditional seals. This technology is more durable than alternative solutions, eliminating the possibility for roll¬ing or pinching during assembly. Installed into two simple counter-bores, Tube Seals are designed to accommodate radial port-to-port misalignment. Radial interference allows the seal to retain in the counter-bore reducing or eliminating assembly line rework and field warranty claims.
