Request Information
Hydraulic Inserts are for use in hydraulic or fuel systems.  They offer strong, permanent threads and wear-resistant sealing surfaces in soft metal castings or accessories.  They permit repeated installation and removal of port fittings without damage to expensive castings and ports.  KNYDJ hydraulic inserts provide port configurations conforming to AS5202 (formally AS10050 and MS33649).
