Where to get Zerk fittings

powerpace · Aug 27, 2013

I have never had to replace a Zerk because it broke. I'm talking many hours on farm and ranch situations. Twenty tractors and implements. I have had to replace them because of being worn down by foliage when picking corn and beans. Are the Zerks not protected by guards?
Lowe's also has Zerks.

My take on it is ($.02), Kioti uses the British thread pattern knowing that a standard tapered metric/SAE is close enough that if you screw it in it makes for a tight fit and will not loosen off or back out, Kioti does that on some parts on the tractor I have noticed, kind of smart if you ask me.

This is something that crossed my mind but wouldn't that ruin the threads on the tractor? Or are they close enough so that forcing it in just kinda makes new ones?

Ya they are protected but I've had zerks just loosen and fall out. Also, from the posts I've seen on this subject, usually zerks break off when trying to get a grease gun un-stuck.

Yeah, that is what I have seen, the zerks are softer than the other part and the threads are real close so not much distortion to the threads happen, it is not like it is forced all the way through the inserting/tightening process.

I could have sworn that I posted this last year, but a search turned up nothing.

You can buy zerk fittings from oringsandmore.com Most fittings on the Kioti are "1/4 BSP"

Straight ones are $17/10 so much cheaper than the dealer. If you want to get crazy, they also have them in stainless-but they are $$$$$$$$$ and will probably break more.

I find two different British thread types, 1/4"-19 and 1/4"-26. Which is the correct one or these tractors?

At BSP Grease Fittings - Orings and More, there is a BSP Grease Fittings heading on the left side of the page. Click on that and the first listings are for 1/4"-26, $15.5 per 10 BSF. Then as a top seller listing on the right side of the page, there are BSP 1/4" straight, $17 per 10 and also 1/4"-26 BSF Straight.

You specify BSP, but on this website the BSP entry point leads to BSF initially. And then farther down there are 1/4" BSPs. Can I assume the 1/4" BSPs with no thread listed and $17 for 5 each are the correct ones?

Thanks

Well crap. I just realized after looking at your post that I posted the wrong size. You need BSP 1/8 not 1/4. To make matters worse, I can no longer edit my first post!

BTW, what you were looking at was BSF (Fine) and not BSP (Pipe or parallel depending on who you talk to). Confused yet? I apparently still am!

I am now good- Thanks! Have it figured out and will order some to have around- just in case. My tractor is new and there are 2 fittings, front axle pivot and another somewhere in the rear that will not take any grease. So need to figure these out and having replacements may help. From reading other posts I may need to do some moving of pieces to get the grease flowing.
