KPALAG 6.0L Powerstroke IPR Socket & High-Pressure Oil Rail Leak Test Kit with Seals

A complete KPALAG service kit that includes a 6.0 IPR valve socket, oil rail adapters, air test fitting and seals to test, remove and replace the injector pressure regulator on Ford 6.0L Powerstroke engines.

This KPALAG kit bundles the specialty tools and replacement seals needed to diagnose and service the high-pressure oil (HPO) system on 6.0L Powerstroke engines. Made from hardened steel, brass and durable Nitrile components, the set is finished with corrosion-resistant coatings and designed to match factory fitment so you can perform leak tests, swap the IPR and refresh rail seals without sourcing separate parts.

How does this kit help find oil rail leaks quickly?

The included IPR air-test fitting and oil rail adapters let you pressurize the high-pressure oil rail to reveal leaks fast. By isolating the rail and monitoring pressure with a gauge (not included), you can identify failing seals, threads or fittings before reassembly.

• IPR air test fitting adapts to rail for pressurization
• Two oil rail adapters to fit common rail ports
• Durable O-ring and backup ring to replace worn seals
• Brass/steel construction reduces leak points during testing

Can I remove and replace the IPR valve with this socket?

Yes — the 6.0 IPR valve socket is machined for the OEM-style IPR valve, providing correct engagement for safe removal and installation. Use a 3/8" wrench or compatible square drive to operate the socket and avoid rounding the valve head.

• Socket sized to match Ford 6.0 IPR valve geometry
• Works with standard 3/8" ratchets or drives
• Reduces risk of valve damage during service
• Quick install/removal for faster shop turnaround

What replacement parts are included and are they OEM-equivalent?

The kit supplies a full set of service items commonly replaced during rail or IPR service: IPR screen, O-ring, backup ring and an additional O-ring seal. Materials like Nitrile and ABS are selected for oil resistance and heat tolerance similar to OEM specifications.

• 1 x IPR valve socket and 1 x IPR air test fitting
• 2 x oil rail adapters for common port fitment
• 1 x IPR screen, 1 x backup ring and 2 x O-rings
• Replaces part numbers 3C3Z-9H529-A, 3C3Z9H529A and AP0035

Who this kit is for: mechanics, diesel technicians and knowledgeable DIYers who work on Ford 6.0L Powerstroke engines (Excursion, E-Series, F-Series 2003–2010). If you need a reliable, single package to test for high-pressure oil leaks, swap the IPR or refresh rail seals while maintaining proper fit and durability, this KPALAG kit streamlines the job and minimizes trips for missing components.
