Park Tool GG-1 Fat Press grease applicator — Silver One Size, thumb-press accuracy for bearings & threads

The Park Tool GG-1 Fat Press is a shop-grade applicator that delivers precise amounts of grease or anti-seize to hard-to-reach bike components using a slim tip and a 3.6 fl. oz (100 mL) canister.

Whether you're maintaining hub bearings, threads, or press-fit parts, the GG-1 gives you controlled placement without mess. Built to work with Park Tool grease and anti-seize, the press attaches quickly and fits tubes or its included canister for portable, tidy lubrication. Its narrow outlet helps you avoid over-application and keeps grease off brake surfaces and suspension bushings.

How does the GG-1 make applying grease easier?

The GG-1 replaces messy spooning and imprecise squirt bottles with a thumb-press mechanism that meters lubricant where you need it. Its small tip concentrates flow, so you use less product and reduce cleanup time.

• Thumb-operated plunger for single-handed control
• Narrow tip for accurate placement into bearings and threads
• Compatible with Park Tool grease/anti-seize tubes and included 100 mL canister
• Durable construction for repeated shop use

Can I use different lubricants with this press?

Yes — the GG-1 is designed to work with Park Tool greases and anti-seize compounds and can be mounted on compatible tubing. The press also ships with a 3.6 fl. oz (100 mL) canister so you can switch products quickly at the bench.

• Included 100 mL canister for standalone use
• Attaches to Park Tool grease and anti-seize tubes for refillability
• Tip opening sized for thicker shop greases and anti-seize pastes

What maintenance or care does the GG-1 require?

Keep the tip clean after each use to prevent clogging and cross-contamination between lubricants. Store the press with the cap on or inverted in a parts tray to protect the nozzle and ensure long life.

• Wipe tip and plunger after use to remove residue
• Store upright or capped to prevent drying and contamination
• Inspect seals periodically—replace if leaking or worn

How does its size and compatibility suit workshop flow?

The one-size GG-1 fits most hands and stalls, offering a compact footprint for busy benches. The included canister keeps a consistent supply on hand while still allowing quick attachment to full-size tubes when you need bulk capacity.

• One-size, ergonomic design for comfortable use during long jobs
• Small footprint saves bench space and fits into tool rolls
• Quick-change between canister and grease tubes for workflow flexibility

Who is this for: The Park Tool GG-1 Fat Press is ideal for bike mechanics, home enthusiasts, and workshop technicians who want cleaner, more accurate lubrication. If you regularly service hubs, pedals, threaded components, or assemblies where excess grease is a problem, this applicator reduces waste, speeds service, and keeps critical surfaces clean.
