Buying Guide

What should you consider when choosing teflon seals for a power steering pump?

Match the seal to your system type (Type II vs Type III) and the fittings size. Teflon seals offer low friction and good chemical resistance, but incorrect sizing or mismatched system type can lead to leaks or seating issues. Consider whether you need a full pump replacement, a seal-only kit, or a combination kit with o-rings and copper washers.

Seal material and compatibility

Teflon seals perform well in high-pressure hydraulic environments but verify that your seals are designed for the correct temperature and fluid exposure. For high-heat applications, materials like HNBR in accompanying O-rings may improve durability. If your system uses Buna N o-rings alongside teflon, ensure compatibility to avoid swelling or hardening.

Installation considerations

Some kits include tools to simplify installation on Type II or Type III fittings. If you’re a DIYer, a kit with installation tools can reduce time and errors. For Jaguar or specific model seals, consider model-specific kits to preserve fit and performance.

Remanufactured pumps vs. seals

Remanufactured pumps provide a complete replacement with seals, O-rings, and valves, reducing part hunting. Seals-only options are usually cheaper but require more precise sizing and knowledge of your current pump’s geometry. Choose based on budget, skill, and vehicle requirements.

Fit verification and mileage expectations

Always verify vehicle compatibility: year, model, and engine type may influence which seals or pumps fit. For Jaguar or classic European models, model-specific seal kits may be essential. For modern vehicles, ensure the pump, reservoir, and hoses align with the existing hydraulic routing.

Practical quick-check questions

  • Do I know my power steering system type (Type II vs Type III)?
  • Is a full pump replacement needed, or are seals sufficient for the fix?
  • Does the kit include installation tools or require separate tools?
  • Is the kit compatible with my vehicle’s make and model?
  • Are there any known fit issues with aftermarket remanufactured pumps?

Short FAQ

  • What is the advantage of teflon seals in power steering? They offer low friction and good wear resistance, helping maintain hydraulic pressure and reduce leaks.
  • Can I mix seal types in a system? It’s best to use seals designed for the same system type to avoid compatibility issues.
  • Are remanufactured pumps reliable? They can be, especially when triple-tested components are used, but verify compatibility with your vehicle before purchase.
  • What size should I look for in Type III fittings? Verify the 16mm measurement and the specific ID/width your pump requires.
  • Should I replace O-rings and copper washers with a kit? If you’re performing a seal upgrade, a kit including o-rings and washers can ensure proper sealing.
