Restore proper injector sealing and reliable diesel engine performance with this Genuine Nissan Injector Thimble Seat Copper Washer, designed for Nissan Patrol GQ Y60 and GU Y61 models fitted with TD42, TD42T, and TD42Ti engines. This OEM copper washer sits at the base of the injector inside the cylinder head, creating a critical seal between the injector and combustion chamber.

Over time, injector washers can compress, harden, or corrode due to extreme combustion heat and pressure. A worn or reused washer can lead to compression leaks, carbon build-up, hard starting, rough idle, and reduced engine efficiency. Replacing these washers whenever injectors are removed ensures proper sealing and prevents long-term engine damage.

Manufactured to genuine Nissan specifications, this direct-fit copper washer provides accurate injector seating, reliable sealing performance, and long-lasting durability under high-temperature diesel conditions.
