Is thier a warranty on this? The screws fell out of it.

Yes it has a warranty. Manufacturer’s warranty can be requested from Amazon customer service. Check out the Amazon page for more info. However, I just have to ask, you have a grease gun, can swap out the coupler but need warranty work to reinstall a couple of screws?

Can these be rebuilt like loc n lube

No! The rubber seal is a crazy proprietary shape. Last slightly longer than the warranty , then seal disintegrates. Lumax won't sell the seal separately.

What size coupler do you need to attach the lumax to the grease gun hose? my grease gun hose will not screw directly onto the lumax

1/8 npt is what my grease gun had and it threaded on good luck
