• Standard Ignition SK139 diesel fuel injector installation kit for service work

Detailed Description

Standard Ignition SK139 focuses on the sealing components needed during diesel injector service. The kit uses Viton-based O-rings to handle heat exposure while maintaining a secure seal at the injector and fuel rail interface.
