Product Information
Grease Gun Coupler
The Grease Gun Coupler is a detachable component that connects the grease gun hose to the fitting on the equipment being lubricated. It is designed to provide a tight seal to prevent grease leakage and ensure efficient lubrication. The coupler is made of durable materials that can withstand high pressures and harsh working conditions.
Product Usage Instructions
How to remove an old coupler
- If the front half of the old coupler is still attached to the grease gun, remove it by unscrewing it counterclockwise.
- If the back half of the old coupler is still attached to the grease gun hose, try to remove it by hand. If it won’t come off, proceed to the next step.
- Use a vice to hold the back half of the old coupler firmly in place.
- Use pliers to twist and pull the hose counterclockwise to release it from the coupler.
- If the hose is still stuck, use a blow torch to heat up the coupler for about 20 seconds. Then, use pliers to twist and pull the hose counterclockwise to release it from the coupler.
- Use a rag or gloves to protect your hands from any hot parts.
- Once the old coupler is removed, inspect the hose and clean it if necessary.
- Attach a new coupler by screwing it clockwise onto the grease gun hose until it is tight.
- Use a wrench to tighten the coupler until there is only one set of wrench flats left visible.
Note: If you are having difficulty removing the old coupler, you may need to use a combination of tools and techniques, including pliers, a blow torch, and elbow grease. Be patient and take your time to avoid damaging the hose or the coupler.
COUPLER WON’T FIT?
Before assuming your grease gun has incompatible threads, first check to be sure that the old coupler is removed completely. The LockNLube® Grease Coupler uses a standard 1/8″ NPT thread. To install, you’ll first need to remove your old coupler
On certain grease guns, it’s easy to remove the front half of the old coupler,
but the back half can still be attached to the grease gun hose and can be
difficult to remove.
In this case, the LockNLube® Grease Coupler won’t thread on because the
internal threads from the old coupler are not 1/8″ NPT.
To get the old coupler off, you may need to use some combination of a vice,
pliers, a blow torch, a lot of elbow grease, and maybe a few of your favorite
curse words.
