Dreyoo Complete Grease Fitting Replacement Kit — Galvanized 4-in-1 Dual-Head Tools & Assortment Case

This compact kit bundles hardened, galvanized alloy-steel grease fittings and two dual-head zerk tools in a clearly labeled storage case so you can restore lubrication points on vehicles and equipment without hunting for parts. Every fitting is precision-machined for a tight seal and smooth grease flow; the two multi-function tools combine cleaning, extraction, installation, and thread restoration in one rugged package.

How will this kit fix a clogged or damaged grease fitting?

The included 4-in-1 dual-head tools are built to clean, extract, re-thread, and install replacement fittings, so you can revive a blocked or rounded zerk without replacing the whole component. Use the extractor end to pull out a damaged zerk, the re-threading function to restore the port, and the installation head to seat a new fitting snugly.

• Two dual-head tools: fit common SAE and metric thread patterns for versatile repairs
• Extractor and re-thread features: remove seized zerks and restore port threads
• Precision fittings: 1/8"-27 NPT, 1/4"-28 SAE-LT, M6x1, M8x1 included for fast replacement
• Protective caps: 20 caps to keep new fittings clean after installation

Which fittings and sizes are included, and why does that matter?

This kit covers the most common SAE and metric grease ports so you don’t need multiple assortments. Having both straight and 90° angle zerks lets you replace fittings in tight or angled grease points on tractors, trucks, or construction gear without improvising.

• 10 × 1/8"-27 NPT straight and 5 × 1/8"-27 NPT 90° fittings for NPT ports
• 10 × 1/4"-28 SAE-LT straight and 5 × 1/4"-28 SAE 90° fittings for SAE ports
• 10 × M6x1 and 10 × M8x1 straight metric fittings for European and modern equipment
• 20 protective caps (10 red, 10 yellow) to prevent contamination after service

How durable and transportable is this grease zerk tool kit?

All fittings and tools are made from galvanized alloy steel for corrosion resistance and high torque tolerance, so they stand up to repeated workshop or field use. The compact, labeled storage case organizes components so you can grab the exact fitting or tool and go — it fits in a toolbox or truck compartment.

• Galvanized alloy-steel construction resists rust and wear
• Clearly labeled compartments speed part identification during repairs
• Compact case protects parts from dust and moisture while on the move
• Tools sized for common hex fittings for fast, secure installations

What routine maintenance tasks can this kit simplify?

Use it to maintain lubrication systems: clear blocked zerks, replace worn fittings, re-thread ports after cross-threading, and cap exposed fittings to prevent dirt ingress. Regular upkeep keeps grease flowing to bearings, pins, and pivots for smoother operation and easier future servicing.

• Clean and clear grease lines and ports to restore proper lubrication
• Replace damaged or missing zerks to prevent premature component wear
• Re-thread stripped ports to avoid costly housing replacements
• Cap fittings after service to protect grease points from contamination
