Is there a better way to deal with clogged fittings than busted High Pressure Grease Fitting manufacturer and busted knuckles?
We think so.
Sometimes just having the Grease Coupler is enough to blast through whatever crud is plugging up your grease fitting. As long as your grease gun and hose can handle pressures up to 10,000 psi, the coupler will too.
On older Grease Couplers, a clogged fitting can create back pressure in the hose and coupler, making it hard to depress the thumb lever and remove the coupler. We suggest applying some light pressure to the thumb lever with a pair of pliers - it should pop right off. Resist the urge to twist or jerk the coupler to the side, because this can damage the seal.
Sometimes, a clogged fitting needs some time and work to really work itself out. We started selling Grease Buster products for that reason. They're the toughest tool we've found for clearing clogged fittings, and they truly get the job done. Load up a Grease Buster with Liquid Wrench, Mineral spirits, or any penetrating oil, and tap the piston a few times. As tempting as it may be, don't smash the thing with a hammer - the point is to use vibration to get the oil in there and slowly break up the clog, not to blast it through your bearings. We also sell a pneumatic piston for the Shop Size Grease Buster that is compatible with pneumatic hammers.
Clearing Tough Clogs – the DIY way
If you’re looking for a do-it-yourself solution, try taking the Zerk off and digging around with a wire or a welding rod to clear any clogs. You can use a penetrating oil to help loosen things up and blast some air on it to clear it out. If that doesn’t work, you can always swap out the Zerk for a new one.
