## Description

G.Coupler – The Original Professional Self-Locking Grease Head for Zerk Attachments – Easy to Fix and Remove (M10 x 1) : desertcart.co.uk: Automotive

Review: Wecht - Works perfect and doesn't leak where standard ones do and can get them in blind holes aswell.
Review: Worth every penny - Tried a few cheaper ones and none lasted more than a week! I've been using this almost daily for a few months and still working like new. Definitely worth the extra expense over cheaper copies

## Features

- FOR INDUSTRIAL EQUIPMENT: Our original grease gun with patented locking mechanism is an ideal tool for professional use for all machinery that requires lubrication at construction sites, mines, farms, forests, maintenance facilities, workshops or anywhere in the field
- MESS FREE, NO FRUSTRATION - Big jobs can easily get messy, especially when working with industrial supplies and complicated machinery. Our hands free grease attachment is designed to help you eliminate waste and avoid messy, uncomfortable and ineffective greasing operations
- FUNCTIONAL: Choose from M10x1, 1/8" BSP or 1/8" NPT thread grease guns, compatible with all available brands and local specifications. Our G.COUPLER fits all Zerk SAE and metric (DIN) grease guns and works with battery, electric, pneumatic and manual grease guns
- EASY AND QUICK - Press the grease gun trigger and connect it to your desired Zerk fitting. The lever mechanism locks the G.COUPLER to the Zerk, creating a watertight seal to the joint. Press the trigger again to release: No more twisting or pulling to detach the grease pump from the machine, even when working under pressure (maximum operating pressures of 690 bar / 10,000 psi).
- UNIQUE FEATURES: Our G.COUPLER hands-free coupler is the leader in lubricant dispensing technology. Also available is a version with our G.SPARES maintenance kit and a longer version (+50mm) for those hard to reach Zerk fittings

## 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
