Bravex Pneumatic Grease Gun Automatic — Quick-Release Coupler, Continuous-Cycle, 18" Hose

The Bravex Pneumatic Grease Gun Automatic with Quick-Release Coupler delivers continuous, high-pressure grease flow for cartridge or bulk filling, reducing pump fatigue and speeding lubrication tasks.

This professional-grade pneumatic grease gun combines a 14 oz. cartridge and bulk-suction capability with a continuous-cycle mechanism and quick-release coupler so you can keep machines lubricated with minimal stops. Built from cold-drawn steel and fitted with an 18" reinforced flex hose and a rigid 6" extension, it’s designed for heavy workshop, farm, marine and industrial use. The tool balances flow rate (4 CFM @ 90 PSI) with a 1/4"-18 NPT female air inlet, offering reliable performance on frequent lubrication jobs.

How does the continuous cycle make daily lubrication faster?

The continuous-cycle mode lets you pump grease steadily without repeated trigger resets, saving time when servicing multiple fittings. It also reduces operator hand fatigue and maintains consistent pressure at the coupler for uniform grease deposition.

• Continuous pumping for multi-zerk jobs
• O-ring sealed high-pressure piston minimizes leak-back
• 4 CFM @ 90 PSI air consumption balances power and efficiency
• Recommended 3/8" air hose keeps airflow stable

What loading and sealing options prevent mess and downtime?

The Bravex grease gun accepts both standard 14 oz. cartridges and bulk-suction filling so you can choose the most convenient refill method for your shop. Cold-drawn steel canister and precision ID reduce the chance of grease tracking or leakage during bulk fills, and piston O-rings help retain pressure and stop bleed-back after pumping.

• Two-way loading: cartridge or bulk suction
• Cold-drawn steel tube for low ID variance and durability
• Piston O-ring sealing to prevent grease leakage from the pump head
• 20-mesh air inlet screen protects internal components

Why use the quick-release coupler and how to avoid a stuck nozzle?

The heavy-duty quick-release coupler speeds connection to zerk fittings and keeps a tight seal under pressure for effective grease transfer. If the nozzle becomes difficult to remove, it’s typically due to trapped pressure in the hose or coupler — a quick unload step makes removal simple.

• Untighten the hose/nozzle slightly to relieve trapped pressure before removal
• Press down the ball valve in the pump head vent or loosen the head cap to purge air if pumping stops
• Consider a manual unload coupler to reduce clamp tension for frequent uncoupling
• Includes spring-guard on the 18" flex hose to prevent kinking and wear

What accessories and specs matter for workshop compatibility?

This gun includes an 18" heavy-duty reinforced flex hose with spring guard and coupler plus a 5-1/2" hardened metal extension tube and a sharp nozzle tip for precise delivery. Key dimensions and fittings ensure compatibility with most air systems and service rigs.

• Capacity: 14 oz. cartridge and bulk suction
• Flex hose: 18" long with spring guard; stiff nozzle length: 6"
• Air inlet: 1/4"-18 NPT female; recommended hose: 3/8"
• Spout tip: 1-1/2" L x 9/16" Dia; canister: 10-7/8" x 2-1/4" Dia

Who is this for: The Bravex Pneumatic Grease Gun is built for mechanics, fleet technicians, farmers, marine service crews, and industrial maintenance teams who need a durable, high-throughput lubrication tool. It’s ideal when you require continuous pumping, cartridge or bulk filling flexibility, and a robust hose/coupler system to reach multiple grease fittings quickly and reliably.
