Double Handle Grease Gun Coupler, 2 Pack Quick Lock and Release Upgraded Grease Gun with 30cm Hose, 12000 PSI with Standard 1/8" NPT

The lock works better than expected, but the description doesn't tell you it's a metric fitting, they send a 6" hose with it which is pretty much useless. It does fit the regular hose, but it seeps a bit of grease around the connection. Other than that I keep a grease needle in it all the time and it works beautifully, it's a grease gun you won't get grease everywhere if you don't use it!

Because you clamped on it didn't pop off anyway s from the grease through it

When using these alot occasionally the teeth that lock onto the zerk fittings will come out of their seat making the coupler inoperable. The only way to fix it is to either shove it down onto a hard surface or seat it onto another fitting

I thought It would be easier to fit on fitting by squeezing lever . It doesn't you still have to push it on like any other

Works great !!!

I do mobile services on heavy duty and material handling equipment and this little thing is absolutely wonderful for being able to "one hand grease gun." I'm old school and don't use pneumatic grease guns so unsure how well it works on one of those, but on a hand pump grease gun it's quite nice especially for grease zerks that are in less than ideal condition/dirty. Greatly reduces the amount of grease that escapes out the side of less than ideal zerks. It does obviously lessen the angle in which you can get it on to which sometimes makes it impossible to be used in some places.

The coupler works as stated with no issues when I've used it. The squeeze handles make it easy to get on the zerk and you can tell when it's secured.

I haven't been able to use this yet, so I'll comment on what I've noticed, and update the review with anything notable once I do use it.This seems like a solid coupler. The finish is nice, and having two handles should make locking and releasing the coupler much easier. I have been using the one that came with my grease gun, and it's hard to remove once you get it into place.

Se zafa en algunas graseras del auto que engrase, no sé si la causa es la grasera o el acoplador que nos ocupa, esto lo podría saber comprando con el acoplador de mayor costo (se supone que mayor costo es mayor garantía) que se ofrece, pero no pienso gastar en eso. Gracias

Installed on battery operated grease gun works great
