Brand-new molded OEM PCV Valve vacuum hose for all 1986-1987 Buick Grand National, Vin 7 Turbo Regal, and 1987 GNX. Replaces GM #25535554
This OEM PCV hose features:
- Fuel and Oil compatible GM 6165M specification rubber polymer
- Correct 11/32" diameter
- Molded 90 degree elbow and molded offset bends to the PCV valve
- Aramid fiber reinforcement to prevent ballooning or collapse
It is important to note that this Molded OEM PCV Vacuum hose is layered with Aramid reinforcing fibers so that it will not collapse under vacuum. Because of this special rubber polymer, it is specifically designed for this application. It will not swell, nor blow off under boost pressure.
Using cheap non-reinforced silicone knockoff hoses may swell up/balloon and blow off under boost pressure.
