RKX 2.5L Vacuum Pump Rebuild/Seal Kit for VW Audi — Viton Double-Lip Seals & Full Gasket Set

RKX 2.5L Vacuum Pump Rebuild/Seal Kit is a complete gasket and seal set engineered to reseal VW and Audi 2.5L vacuum pumps and stop oil leaks without replacing the entire pump.

If your Volkswagen or Audi with a 2.5L engine is showing oil at the vacuum pump or losing vacuum, this RKX kit provides a cost-effective alternative to buying a new pump. The kit contains precisely molded seals and all necessary gaskets to rebuild the pump’s sealing surfaces. RKX uses high-performance fluorocarbon (Viton) materials and double-lip technology on the primary seals to resist heat, oil exposure, and wear common in these engines.

How will this kit stop oil leaks from my VW 2.5L vacuum pump?

The RKX kit replaces worn or hardened pump gaskets and seals that allow oil to migrate out of the pump housing. The included Viton seals maintain elasticity at high temperatures and restore proper sealing contact. Replacing the seals removes the most common source of oil leaks without machining or expensive parts replacement.

• Double-lip Viton pump seal to block oil and retain vacuum
• All mating gaskets for housing and cover to prevent seepage
• Precision injection-molded components for consistent fit
• Lifetime limited warranty on gaskets for long-term confidence

Which vehicles and pumps are compatible with the RKX 2.5L rebuild kit?

This rebuild kit is designed for Volkswagen and selected Audi models featuring the 2.5L inline-five engine vacuum pump configuration. It fits OEM-style pumps used on many Jetta, Beetle, Golf, Rabbit, Passat, and certain Audi TT RS and RS3 applications. Verify your pump geometry and part fitment against the included gasket set before installation.

• Compatible models: VW Jetta, Beetle, New Beetle, Golf, Rabbit, Passat
• Also used with Audi TT RS and RS3 2.5L pumps where applicable
• Designed to replace original factory seals and gaskets
• Not a full pump assembly — intended for reseal projects

What’s included and what tools are required to install this RKX kit?

The kit includes the full set of internal gaskets and the primary injection-molded Viton seals needed to reseal the pump. It does not include bolts or the vacuum pump housing to keep costs down and focus on replaceable sealing components. Installation requires basic mechanical skill, torque tools, and a clean work area; follow vehicle service manual procedures for disassembly and reassembly.

• Included: Viton double-lip seal(s), all housing gaskets, O-rings as required
• Not included: mounting bolts, replacement pump body, or specialty tools
• Recommended tools: torque wrench, RTV remover, gasket scraper, basic hand tools
• Estimated time: 1–2 hours for a competent DIYer or technician

Why choose RKX seals instead of buying a new vacuum pump?

Resealing a functioning pump restores engine sealing at a fraction of the cost of a new pump. RKX focuses on high-quality materials—military-grade fluorocarbon—and precision molding to extend service life under engine heat and oil exposure. The kit’s limited lifetime warranty on gaskets reflects confidence in material durability and fitment accuracy.

• Significantly lower cost than full OEM pump replacement
• High-temp, oil-resistant Viton with double-lip design for durability
• Complete gasket set prevents future seepage when installed correctly
• Minimal downtime: quick reseal versus pump replacement

Who is this for: This RKX 2.5L Vacuum Pump Rebuild/Seal Kit is aimed at VW and Audi owners, independent shops, and DIY mechanics who have a functioning 2.5L vacuum pump that is leaking oil or losing vacuum. It’s ideal when the pump’s mechanical components are sound and only the seals or gaskets need replacement. If the pump rotor or housing is damaged, a full pump replacement may be required instead of a reseal.
