Bravex Pneumatic Grease Gun — Continuous-Cycle 14 oz Cartridge/Bulk, 18" Hose & Quick-Release Coupler

This pneumatic grease gun combines a 14 oz. cartridge capacity with bulk-suction capability and a continuous-cycle piston to keep grease flowing with minimal interruption. Built from cold-drawn steel and fitted with an 18-inch reinforced hose, a 6" stiff nozzle and a quick-release coupler, it’s engineered to reduce leaks and withstand workshop demands. The unit runs efficiently at 4 CFM @ 90 PSI and accepts standard 1/4"–18 NPT female air fittings.

How does the continuous-cycle design improve everyday use?

The continuous-cycle mechanism keeps the piston operating smoothly without frequent resets, so you can maintain a steady flow of lubricant on repetitive jobs. Fewer stop-starts save time and reduce operator fatigue during long maintenance sessions.

• Continuous-action piston for uninterrupted greasing
• O-ring sealed pump head minimizes pressure loss and leakage
• Accepts both 14 oz. cartridges and bulk suction filling
• Efficient air consumption of 4 CFM at 90 PSI

What features prevent grease leakage and clogging?

The canister is machined from cold-drawn steel, giving a consistent internal diameter that reduces leakage when using bulk fill. The pump head uses an O-ring sealed high-pressure piston to stop seepage, and the included 20-mesh air inlet screen helps keep contaminants from entering the system.

• Cold-drawn steel tube canister for tight internal tolerances
• High-pressure O-ring piston seal to prevent grease seepage
• 20-mesh air inlet screen to block debris from the air supply
• Sharp-type nozzle to improve coupling and grease delivery accuracy

How do I handle common issues like trapped air or stuck couplers?

If the gun fails to pump because of trapped air, depress the vent ball valve with a pin while pumping until grease appears at the nozzle, or slightly loosen the head cap while pumping. When a coupler grips a zerk fitting tightly after use, relieve pressure in the hose or loosen the hose/nozzle slightly before removing the coupler to release the clamp force.

• Use a pin on the vent valve or loosen the head cap to purge air
• Untighten the hose/nozzle a bit to unload pressure before uncoupling
• Consider an unload coupler for easier future disconnection
• Follow coupling sequence to avoid damaging fittings

What accessories and dimensions should I expect?

The Bravex kit includes an 18" heavy-duty reinforced flex hose with spring guard, a 5.5" hardened extension tube, and a 6" stiff nozzle for reach into tight grease points. The canister is approximately 10-7/8" long with a 2-1/4" diameter, and the recommended air hose size is 3/8" for proper airflow.

• Included 18" flex hose with spring guard and quick-release coupler
• 5.5" hard metal extension tube and 6" stiff nozzle
• Canister: 10-7/8" × 2-1/4" diameter; spout tip 1-1/2" × 9/16"
• Air inlet: 1/4"–18 NPT female; recommended hose: 3/8"

Who is this for: The Bravex Pneumatic Grease Gun is aimed at mechanics, fleet maintenance teams, farmers, marine technicians, and industrial maintenance crews who need a robust, fast, and reliable lubrication tool. It fits users who want the flexibility of cartridge or bulk filling, demand a leak-resistant metal canister, and appreciate a continuous-cycle drive that reduces downtime during repetitive greasing tasks.
