Grease Gun Needle Tip, Inject Grease into Rubber Boots Bushings, Injector Needle Ball Joints, Bearing Grease Injector Needle Nozzle Dispenser, Grease Needle with Adapter, Needle Grease Fitting

I’m really impressed with this grease gun needle set, especially the angled needle—it’s a game changer! My equipment has grease fittings in super tight spots on the inside, where a straight needle just wouldn’t work. This setup made greasing so much easier, saving me time and cutting down on maintenance costs. I’d highly recommend it!

2-27-25 Update: Upon seeing my Review (original below line), Yirnno Customer Support reached out to me multiple times! They were concerned about my experience and how they could improve. I suggested needles may not need to be so sharp - maybe they CAN be more dull - like the needles on hand air pumps that you insert into basketballs), and still be pushed through rubber grease boots found on cars. And if they needed to remain sharp, maybe warning stickers. And Instructions for use regardless, (needles can usually be removed by unscrewing grease GUN tip some). And to alter ad so it doesn't show application of GREASE to bicycle gears / cogs - they take light OIL instead. Also, that at least some of the tips needed to have wider openings to let more lube out. Yirnno has promised to look into this and make any needed changes.------------------------------------------------------------------------------------------------The 5 Grease Gun Tips by the Yirnno Store came today. While I do work on my own cars, (for the record: Not Teslas and I'm NOT a pro mechanic), I got these grease gun tips to (first) use lubing bicycle WHEEL BEARINGS, or anytime I needed a little grease on other bicycle parts, like a seat post or pedal, crank, or cassette THREADS. I've never put GREASE on a bike's cassette or freewheel gears / cogs, (as Ad pic 5 shows), and my search finds that's NOT good!Quote: "When lubricating your bike drivetrain, you should only lube the chain and not the cassette; applying lube directly to the cassette is not necessary and can actually attract dirt, causing more wear and tear on both the chain and cassette."I rode a bicycle like most kids, and got back into the sport 2 years ago for exercise. I've had to learn all types of bike repairs and maintenance on my bikes, all bought used. I regularly watch several different Youtube bike channels, run by professionals and enthusiasts, including Park Tool videos, and they DO NOT put GREASE on a cassette or freewheel cogs (gears). And when they do use a lubricant, it's a light oil like Tri-Flo or First Step, usually on brake and shift cables and levers, brake pivot points and springs, or bottle cage screws and bolts to prevent seizing or corrosion.The Amazon product ad states:"【𝗚𝗼𝗼𝗱 𝗜𝗱𝗲𝗮 𝗼𝗳 𝗨𝘀𝗶𝗻𝗴 𝗯𝗼𝘁𝗵 𝗕𝗲𝗻𝘁 𝗮𝗻𝗱 𝗦𝘁𝗿𝗮𝗶𝗴𝗵𝘁 𝗡𝗼𝘇𝘇𝗹𝗲𝘀】 Which is a common tool in automotive and machinery maintenance. Good idea of using both bent and straight nozzles to better access tight, hard-to-reach areas."The Yirnno Store packet has 5 tips total - 2 bigger, brass colored Nozzles (1 straight, 1 curved) and 3 NEEDLE grease gun tips, which I've never seen or used before, and quickly learned are very SHARP - likely too sharp! On my cars, I plan to use the NEEDLE tip to go on a ball joint or tie rod end (that doesn't have a grease zerk.) BUT I would avoid puncturing a rubber grease boot, and instead go under it or perhaps between a bearing and a race. Having never seen a needle tip before, I didn't even know if it would fit into my full size grease gun. - It did - snapped right in. However, when I capped and tried to carefully remove it, it didn't come off, my gloved hand slipped from the greasy gun, but removed the cap, then went back forward - and the needle went through my mechanic glove into my hand! After the pain went down and blood dried, but still mad, I got back to it, convinced it was needlessly sharp, and squeezed some grease into a plastic cup, to see the size of the stream. On my grease gun, the grease didn't flow until I had given 3 full pumps, and the grease was the size of pencil lead, a little narrow for my bicycle needs, I thought. Besides, having received 3 of the thin Needle tips, I decided to sand the sharp tip off, to prevent stab #2. lol Oh - and I was going to drill out the straight brass colored tip to increase its size, but my small drill bit wasn't long enough, so instead, I made it's hole bigger by briefly sanding on a 3 1/2 inch angle grinder too - as shown in my last 3 pics.Online, I learned needle tips aren't new, (so I'm trying to accept them, but still, I don't think I'll ever have to use the 2 Needle Tips that I left sharp and capped.) I also watched someone use a needle tip, and learned that to remove it, I can simply unscrew the GREASE GUN END some, and its grip on the needle tip is reduced. (And don't forget to screw the gun tip back in). So, you learn something everyday.As seen in my pic, I found one of the bigger Nozzles to be loose from its grease zerk, so I unscrewed it - You should check yours.
