Technical Ordering Specifications Summary

This document is a Technical Ordering Specification for a static, leak-proof seal component designed for large hydraulic connections, including main control valves, stabilizer ports, and boom cylinder inlets. The seal is identified by Part Number 115526 and is engineered for M24 metric fittings and screw plugs. The primary material composition consists of either soft copper (CU) or a bonded seal (Usit) design, with the specific material determined by the pressure rating requirements of the assembly. The component conforms to DIN 7603-A standard for flat sealing gaskets and features dimensions of approximately 24.7 mm inner diameter (fitted over M24 threads), 32 mm outer diameter, and 2.0 mm thickness.

Procurement guidance emphasizes sourcing genuine components to ensure correct material hardness and compatibility with hydraulic oils, as these seals are critical for preventing high-pressure fluid leaks. Authorized procurement channels include Palfinger Dealers (which manages approximately 350,000 items globally and maintains stocks at European and North American hubs) and independent regional suppliers such as Thompson eParts and CraneWorks, which typically offer fast delivery options for standard M24 seals. Best practice requirements specify that metal seals are intended for single use only, with replacement recommended each time the associated hydraulic fitting or plug is loosened to maintain system integrity.
