CARBYNE Grease Gun Accessory Set, 12 Piece | All-in-One Set: Couplers, Nozzles, Adapters and Flex Hose with Durable Storage Case | Multiple Applications •from a Family Tool Company Based in The U.S.A.

I bought this for work. The different needle sizes and adaptors come in handy when greasing and packing new bearings.

I bought a Milwaukee 12-volt cordless grease gun that came with a standard in-line coupler. I needed to grease the bearings on a utility cart, but the in-line coupler wouldn't work because the grease fitting on the hub is perpendicular to the hub and the wheels are small. I was planning to buy a right-angle coupler only, but I found this set on Amazon and thought it would be good idea to have a full set for any use that I might have. The set is comprehensive and great quality, and it comes in a nice case. The right-angle coupler is a quick-connect type, and it snapped on to the in-line coupler that came with my grease gun without requiring any tools. It worked great, did not leak, and removing it when I was done was just as easy as putting it on.I don't know what the uses of some of the other couplers in the set are, and as another reviewer pointed out, the set did not come with any instructions. However, I always consider it my responsibility to learn how to use a new tool, so I won't let that change my five-star review.

Covers most needs and appears of fair quality for the money.

This well designed set includes every size and shape of nozzle that I'll ever need to properly apply grease to any piece of my lawn and garden equipment and anything else around the garage that tries to squeak or wear from friction. There are adapters to reach those fittings that you would normally need double jointed fingers to get to. There are several styles of needle nose nozzles that can be used to insert grease into rubber boots covering joints or bearings or to simply and very accurately lubricate spots where you don't want excess grease dripping onto belts or something else. The quality of the individual pieces in this set is good enough for anyone needing intermittent use of them. The fifth star was earned by the plastic case which both protects the thinner tips and keeps all the contents in specific cavities where they are easily available when needed.

I think it will work just fine when I need a special setup to grease a hard to reach fitting or bearing. The needle fitting came appart on the first use.
