Four Banded Viton valve guide seals – install by hand.

$12.00

These are the only available banded Viton guide seals for Nortons that press on by hand.  Won’t dry up oil lubrication to the valve stems like Teflon seals can.  The bands insure a tight seal top and bottom and prevent loosening.  Seals should be used on both intake and exhaust – intake to prevent pulling oil past the guides into the combustion chamber and on the exhaust to prevent spent gasses from blowing past the guides and contaminating the oil.
