## Questions & Answers

**Q: What size fits a Milwaukee 18volt grease gun**
A: Will fit all BSP 1/8th fittings on grease gun hoses.

**Q: Hi I have a Samoa lever gun and wonder what fitting I need.**
A: It depends on the thread on your grease gun, M10 or 1/8" BSP, find this out then get the G Coupler to suit.

**Q: How does it go on a dewalt greasegun**
A: Good day,

The G.COUPLER replaces the standard Coupler which is screwed on to the end of the flexible hose.
The original coupler is unscrewed and the G.COUPLER (either BSP, NPT or M10 thread) is screwed on in its place.

We have attempted to identify from the DeWalt site what thread version they specify, without success.

Typically, UK products will use BSP / US products use NPT / European and rest of the world products typically use M10.

We recommend you confirm directly with either the specification sheet that came with your Grease Gun or with DeWalt directly.

Thank you for your query.

Regards,
G-PRODUCTS

**Q: Hi I have a alemite a 500 grease gun was wondering which thread size I need to order thanks**
A: It will depend on what thread type your gun is. If it’s imperial, then the 3/8 type should work, if it’s metric (which is probable) then it’ll probably be the 10mm
