FAQ
What does the CNC Fabrication 424013 kit include?
The kit includes five -905 Viton O-rings for cylinder head fittings and three -906 Viton O-rings for HPOP pump fittings.
Will this kit service all fittings on my CNC Fabrication HPOP line kit?
Yes. The kit contains enough O-rings to service all fittings on both 2-line and 3-line CNC Fabrication HPOP line kits, along with additional spare O-rings.
What material are the O-rings made from?
The included seals are manufactured from premium 90-durometer Viton material for excellent heat, oil, and pressure resistance.
Why should I replace HPOP fitting O-rings?
Over time, O-rings can become worn, flattened, or damaged, leading to high-pressure oil leaks that may affect injector performance and engine operation.
Should the O-rings be lubricated before installation?
Yes. CNC Fabrication recommends lubricating all O-rings with clean engine oil before installation to help prevent damage during assembly.
Will these fit stock HPOP systems?
