Park Tool GG-1 Fat Press handheld grease dispenser — Silver, 100 mL canister, precision tip

Park Tool GG-1 Fat Press is a shop-grade handheld dispenser that delivers clean, precise doses of grease and anti-seize for bike maintenance and mechanical work.

The GG-1 Fat Press is built for technicians and home mechanics who want controlled lubrication without mess. It accepts a 3.6 fl. oz (100 mL) canister and can also be fitted to Park Tool grease or anti-seize tubes, giving you the flexibility to work with different compounds and viscosities. Its slim, small-tip opening helps place lubricant exactly where it’s needed—seals, bearings, threads, and mating surfaces—while the durable silver finish and ergonomic body stand up to repeated shop use.

How does the GG-1 Fat Press improve accuracy when applying grease?

The GG-1’s narrow tip and positive dispensing mechanism let you target small gaps and tight bearings without over-application. That precision reduces waste and keeps nearby parts clean so reassembly is faster and neater.

• Small tip opening for pinpoint placement
• Controlled pressure minimizes sudden gushes
• Compact body improves hand control in tight spaces

Can I use different greases or anti-seize compounds with this tool?

Yes — the GG-1 is compatible with the included 100 mL canister and can also be installed on Park Tool tubes. That adaptability lets you switch between greases, anti-seize, and specialty lubricants depending on the job.

• Includes 3.6 fl. oz (100 mL) canister for immediate use
• Accepts Park Tool grease or anti-seize tubes for refills

What makes the GG-1 suitable for shop and home use?

Durable construction and a straightforward dispensing action make the GG-1 dependable under frequent use. It’s simple to operate, easy to swap cartridges, and compact enough for toolbox storage or a workshop bench.

How do I maintain and store the Fat Press between uses?

Wipe the tip after each use to prevent buildup and cap or reattach the canister to avoid contamination. Store the GG-1 in a dry place at room temperature, away from direct sunlight and extreme heat.

• Clean tip with a rag after dispensing
• Keep spare canisters or tubes sealed until needed
