Grease coupler four-jaw PRESSOL M10x1 model 12631 for grease fittings

PRESSOL four-jaw grease coupler M10x1 model 12631 is a mechanical accessory designed to attach securely to standard M10x1 grease fittings. It creates a stable connection between the grease gun and the grease nipple to allow controlled injection of lubricants into bearings, joints and other service points. The coupler’s four-jaw design helps maintain engagement during pressure application and reduces the risk of slippage or loss of seal during lubrication operations.

Advantages

The four-jaw construction provides firm mechanical grip on compatible grease nipples and supports continuous pressure without disconnecting. The threaded M10x1 connection offers compatibility with many grease guns and adapters used in workshops and industrial maintenance. The coupler is built for repeated use under workshop conditions and simplifies accurate lubricant delivery to confined or hard-to-reach fittings.

Подходит для

• Перекачка смазки в подшипники и шарниры
• Обслуживание промышленного и автомобильного оборудования
• Ремонтные работы в мастерских и сервисных центрах
• Обслуживание сельскохозяйственной техники и строительной техники

Key specifications

• Thread interface: M10x1 (female thread for attachment to grease guns/adapters)
• Coupling type: four-jaw mechanical coupler
• Intended connection: standard grease nipples compatible with M10x1 couplers
• Primary use: manual grease injection for bearings, joints and fittings
• Material and finish: workshop-grade metal construction suitable for repeated use

How to use

Attach the coupler to the grease gun by threading the M10x1 interface until it is securely seated. Align the four-jaw end with the grease nipple and press the coupler onto the fitting until jaws engage around the nipple. Operate the grease gun with steady pressure to deliver lubricant while monitoring for a stable seal between coupler and nipple. After lubrication, release pressure, withdraw the coupler and inspect the fitting for proper grease distribution and any residue.

Usage recommendations

Verify compatibility of the M10x1 thread and the grease nipple type before use. Use appropriate personal protective equipment and follow the grease gun manufacturer’s instructions for safe operation. Periodically inspect the coupler jaws for wear and replace if engagement becomes unreliable to maintain a consistent seal and prevent leakage.
