EVRBUL IPR Valve Socket 1-1/8" (29mm) Deep 3/8" Drive – 7.3L Powerstroke Fit, Heat‑Treated 630 Stainless

EVRBUL's 1-1/8" (29mm) deep socket is a dedicated install/removal tool for IPR (injector pressure regulator) valves on Ford 7.3L Powerstroke engines, engineered to fit recessed valve locations and work with a standard 3/8" drive torque wrench.

Built from heat-treated 630 stainless steel, this specialty socket combines corrosion resistance with high hardness so it stands up to repeated use around fuel-system components. It’s sized specifically for OEM IPR valve fittings and comes ready to pair with commonly available hand tools, making it an efficient choice when servicing E-series vans, Excursion models, and Ford Super Duty trucks that use the 7.3L Powerstroke.

Which Ford models and years will this socket fit?

This socket was manufactured to match the IPR valve dimensions used across many Ford 7.3L Powerstroke applications. It covers a broad range of E-Series vans, Super Duty trucks and the Excursion where the OEM valve design is present.

• Ford E350: 1995–2003
• Ford E450: 2000–2002; E550: 2002–2003
• Excursion: 2000–2003
• F-250 / F-350: 1994–1996 and Super Duty 1999–2003; other F Super Duty 1994–1996

How does the socket make IPR service easier?

The deep 29mm profile reaches recessed valve bodies while the 3/8" drive accepts a common torque wrench or breaker bar. Designed to reduce stripping and provide a positive engagement, it simplifies removal and installation in cramped engine bays.

• Deep well design accesses recessed valves without extensions.
• 3/8" drive compatibility with standard torque wrenches.
• Precise fit reduces risk of rounding valve hexes.
• Single-piece construction resists bending under torque.

What material and construction features improve durability?

EVRBUL uses 630 stainless steel and applies heat treatment to increase hardness while retaining corrosion resistance. This construction resists wear from repeated torque cycles and exposure to fuel residue and shop chemicals.

• 630 stainless steel for strength and rust resistance.
• Heat-treated to raise surface hardness and longevity.
• Machined to tight tolerances for secure valve engagement.
• Single-piece socket reduces failure points.

Which OEM or aftermarket part numbers does this replace?

If you’re matching part numbers, EVRBUL’s socket corresponds to a range of IPR valve references used by Ford and aftermarket suppliers. That makes it a direct-fit replacement tool when you need the correct hex engagement for removal or installation.

• Replaces common IPR references like F81Z9C968AA and F81A9C968AA
• Compatible with F81Z9C968AB, F81Z-9C968-AB and F5TZ9C968A
• Also matches numeric codes 1841217C91, 1829856C91, 1836412C91, 1841086C91
• Aftermarket equivalents: 931-308 / 931308

Who is this for? Technicians, home mechanics, and fleet maintenance teams who service 7.3L Powerstroke diesel engines will find this socket a useful addition to their toolbox. It’s particularly helpful for anyone facing limited access to the fuel system’s regulator valve where a precise, durable 29mm deep socket with 3/8" drive is needed. The tool ships as a single dedicated socket and is aimed at users replacing or reinstalling IPR valves using standard workshop hand tools.
