GLEXQLAO Injector Seal Installer Kit 8-Piece — 34720 Steel Tools for Teflon Injector Seals, Resizers & Pushers

The GLEXQLAO 34720 Injector Seal Installer Kit is an 8-piece steel tool set that lets you replace Teflon injector seals accurately and install them to factory fit without damaging the seal or injector tip.

If you service fuel injectors or perform routine intake and fuel-system maintenance, getting injector seals seated correctly prevents leaks and rough running. This kit includes purpose-built pushers, stretchers and resizers sized for a wide range of modern injectors so you can fit single and dual Teflon seals cleanly, rapidly and with minimal trial-and-error.

Which injectors and vehicles will this kit work on?

The GLEXQLAO 34720 set is designed for broad, OE-style compatibility with many common fuel injector families. It supports many Hitachi, Bosch, Continental and Delphi single- and dual-seal injectors and lists coverage for recent Ford, GM and Subaru engine families.

• Ford injectors from 2011 and newer
• GM engines 2010+ including 1.4L–6.2L applications
• Subaru turbo engines 2014–2019 (2.0L and 2.4L)
• Works with most aftermarket and OE-style Teflon single/dual seals

How do the tools make installation easier and safer?

Each tool in the set is dedicated to a stage of the seal fitment process—stretching, positioning, pushing and sizing—so you avoid nicking or folding the thin Teflon rings. Tools are labeled and hardened steel with a corrosion-resistant finish for repeatable, damage-free use.

• Pilot cone centers and aligns the seal on the injector tip
• Seal pusher moves seals into the groove without deformation
• Resizers compress the seal to exact outside diameter for head insertion
• Clearly marked sizes speed selection and reduce mistakes

What exactly is included and what sizes are covered?

The kit packs eight pieces plus a compact storage case so every component stays organized. You get multiple stretchers and resizers matched to common injector diameters, plus a dedicated seal pusher and pilot to handle initial placement.

• 1 × seal pusher and 1 × pilot cone for alignment
• Two resizers (.312 and .310) for final outside diameter control
• Five seal stretchers (.160, .250, .330, .408, .430) for different seal inner diameters
• Protective storage case for portability and workshop organization

How durable is the kit and how should I care for it?

Tools are manufactured from high-strength steel with a protective coating to resist rust and oxidation so they stand up to shop use. Wipe them clean after use, store in the provided case and lightly oil contact points if storing long-term to preserve the finish and fit.

• High-strength steel construction for durability
• Corrosion-resistant surface treatment extends service life
• Marked tools simplify identification and safe selection
• Compact case protects tools between jobs

Who is this for: automotive technicians, independent mechanics and DIY enthusiasts who rebuild or maintain fuel injectors and need a reliable, repeatable way to replace Teflon injector seals. If you work on late-model Ford, GM or Subaru fuel systems or handle OE-style injectors from major manufacturers, this kit streamlines seal fitment and reduces the risk of leaks from poorly seated seals.
