FORD 6.0L Diesel ~ Single Side Leakproof Nipple Cup/Ball Tube Set (4-Cups, 4-Extreme Duty Viton Seals) ***NOTE*** OVERNIGHT and 2ND DAY SHIPPING ORDERS MUST BE RECIEVED BY 3:00PM CST

The shape and size of every single part of our nipple cups has been designed and tested to insure the best possible seal in both a brand new high pressure oil rail and an old worn out rail. Even in the worst conditions, our nipple cups out-perform the competition and the original OEM design. The other aftermarket options are not only made of soft steel, which will wear out quickly, but they are also smaller than the OEM cups. In an older oil rail, a smaller nipple cup will not seal as well and you will end up with leaks sooner than later.

This Auction Includes 4- Leakproof Nipple Cups and 4- Ultra Heavy Duty Viton O-Rings
A Set of 4 to Rebuild ONE Oil Rail or One Side of the Engine.

Leakproof Nipple Cup Features:

• Patent Pending LeakpFroof Design
• Made of Hardened Tool Grade Steel
• Deflection Groove Diverts Any Oil That Leaks Past the Nipple Cup Seal Harmlessly Away from the Top Injector Seal
• Works With All 6.0L Oil Rails - 2003-2007
• Limited Lifetime Warranty - Guaranteed to be a one time purchase that will last as long as your truck
• Will Never Leave You Stranded With a No Start Condition Due to Failed Top Injector Seals
• Optimized Shape and Size to Seal Better Than OEM or Other Aftermarket Cups in New and Old Rails
• Buy It Once and Be Done. Never Worry About it Again!
