The Final Step in LeakProofing your 6.0L is Here!!
If You're Going to LeakProof Your 6.0L, Don't Forget Your Oil Rails!
MASTER REBUILD KIT Comes With Everything You Need To LeakProof Both Oil Rails, Including The Best Nipple Cup Socket on the Market!
Our Patent Pending Nipple Cups Are Made of Hardened Tool Steel and Feature a Unique Deflection Groove to Direct Any Oil That Gets Past Your Nipple Cup Seals Away from the Top Injector Seal. When your nipple cup seals fail, high pressure oil(500-5000psi) follows the body of the nipple cup down to the seal on your injector, wearing at it from the top down. Our LeakProof cups prevent that so you won't end up with a hot no start.

LeakProof Nipple Cup Features:
+ Made of Hardened Tool Steel That Will Outlast Your Truck!
+ Patented Deflection Groove Diverts Oil That Leaks Past a Worn or Damaged Nipple Cup Seal Away From Your Fuel Injector Seal!
+ Unlimited Mileage, Limited Lifetime Warranty on the Nipple Cups, 2-Year Unlimited Mileage Warranty on the Seals*
Tool Features:
+ Impact Friendly
+ 1/2" Drive to Fit Right on the End of Your Impact Gun & Torque Wrench
+ Limited Lifetime Warranty! You Break it, We Will Replace it.
*YOU MUST REPLACE YOUR TOP INJECTOR SEALS AT THE SAME TIME YOU INSTALL NEW NIPPLE CUPS AND SEALS OR YOU WILL END UP WITH LEAKS! Any warranty claim based on top injector seal failure will need to show that you actually replaced your top injector seals when you installed your LeakProof nipple cups. We Recommend Alliant Power Injector seal kits, which include the top injector seals. ASIN: B009VI58CM http://www.amazon.com/dp/B009VI58CM/?tag=aznproduct-20
The Only Solution on The Market That Deflects Oil Away From Your Top Injector Seals!
Patent Pending Deflection Groove Built Into Our Hardened Steel Nipple Cups Makes Sure You Will Never Have a Hot No Start Due to Failed Top Injector Seals
Our Master Kit Includes: 8- Indestructible Nipple Cups, 8- Extreme Duty Viton Blend Seals, Lifetime Warranty 1/2" Drive Nipple Cup Socket
This Whole Kit Costs Less Than You Would Pay for A Single Oil Rail and is a One-Time Fix!
The Competition's Nipples Are Soft and Small! Ours are Hardened Tool Steel With a Plump, Optimized Shape for Your New or Old and Tired Oil Rail!

Title: Excellent Product and Amazing Customer Service
Review: Ordered this kit for my problematic 2006 F350 6.0l. Very impressed with the quality of the parts and the custom tool to install them. Impressed by the thought and engineering that went into the new design. I'm hoping this will solve any future breakdowns due to bad injector seals. I had mistakenly ordered 2 kits and had sent one back for a refund. Amazon had been dragging their feet getting the refund going as the tracking said it was still in transit after 3 1/2 weeks. I contacted Mark at HHC Diesel to see if they could help. They went above and beyond to help me resolve the issue and even went as far to say they would refund me if Amazon wouldn't help. Great to see a company that values their customers as well as the quality of their product.

Title: The way to go !!!
Review: Absolutely fantastic product. Replaced the nipple cups and seals. The socket is indestructible (or seems to be). I also removed and replaced the seals / 'O'-rings on each injector. The top seal replacement isn't fun but I had the most success removing the snap ring in the top seal with a utility knife (slightly dulled) forcing it into the injector (after removing the seal and allowing the spacer to drop to the bottom) and capturing the end with a small screwdriver and carefully prying it out. After driving the truck for about 15 miles, I came back to the shop and the engine would start (on a 92°F day) in 1.3 seconds. I took the truck out for a drive and at WOT achieved a HPOP pressure reading at the ICP of 3776 PSI. The truck has NEVER run like this and so well. (NOTE : I also replaced the unison ring in the turbocharger at the same time). Thanks HHC Diesel for a GREAT product line.

Title: Less Injector Clatter
Review: I installed these with their tool and following their directions. Immediately after starting the engine up, there is noticeably less injector clatter. These 6.0's are noisy, and after 270,000 miles, the original nipple seals had not failed, but when I put the high pressure rails in the vice to remove the old ones and install the, the old ones were loose and floppy indicating the seals had hardened and shrunk. There had to be some pressure loss, and low pressure here will affect the injector life. After installing these, these fit very snugly, and they don't flop about. My assumption is my injectors are back to getting the correct pressure without any oil bypassing them now. Much quieter when running. Sound like it did when new.

Title: MUST replace it for good ! HHC !!
Review: When I work on replace BOLT head to ARP STUD head and same time replace nipple cup and many other parts. I noticed Ford EOM nipple cup have leak problems and can see the build up the hard oil on case see picture look at black spot place. After 85 hours I done upgrade on 6.0... wow very smooth run and feel strong running... happy I DID !! thank to HCC for improved design. ALSO very BEST replace all O-ring of injectors (inside and outside).

Title: A must have for 6.0 owners!
Review: These nipple cups are awesome! Well worth the money knowing that you will not have another issue going forward. One word of caution when working on the high pressure oil system - once primed, you will need to follow the Ford driving recommendations to purge the air out of the system completely. I am familiar with Caterpillar HEUI engines and thought I had a high pressure leak when in reality it was just a bubble. I took the truck out for an hour of driving at varying speeds and that did the trick. Great product!
