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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wecht *by on Reviewed in the United Kingdom 24 October 2025* Works perfect and doesn't leak where standard ones do and can get them in blind holes aswell. ### ⭐⭐⭐⭐⭐ Worth every penny *by on Reviewed in the United Kingdom 17 January 2026* Tried a few cheaper ones and none lasted more than a week!
