M1.5x5 Buna-N O-Ring, 70A Durometer, Round, Black, 5 mm ID, 8 mm OD, 1.5 mm Width (Pack of 100)

RELOADERS REJOICE! Are your Hornady Lock N' Load bushings allowing the dies to pop out of your press from time to time? Is it especially problematic for your powder measure? These O-Rings are the answer. Sure Hornady will send you a metal shim that supposedly corrects the "slippage" problem, but these work so much better and actually fixes the problem cheaply once and for all. They are slightly thicker than the standard Hornady O-Ring that come on the bushings and assure a tight fit with no movement. These are the rings Hornady should have used in the first place. And at this price for 100 O-Rings and two day shipping with Amazon Prime... how can you go wrong? Life is too short for "good enough" or "workarounds" Just buy them... you will not regret it.

I purchased these because the bobbin winder on an old 1910 Singer 66 sewing machine would not fit what everyone advertised. Those are 5/8, but the bobbin friction wheel is 3/4". I went with a 30mm outside diameter and an inside diameter of 22mm, and they fit well. It's the only "replacement" friction wheel I could find, and it works.

Bummer that I had to buy a 50 piece bag of these for replacing only one O-Ring. I had a small amount of oil weeping from my motorcycle starter, so I measured the old one and found these available online. The OE version costs almost half, but you only get one. I get 50 here, and I can give away a bunch of them to other guys who have the same motorcycle as me (Yamaha TW200). Put a little grease or oil on the new one before installing, seals up tight. cheap cheap cheap easy fix.

There's really nothing wrong with them, ordered to replace some that were torn in my water cooled PC, but turned out to be the wrong size. I'll find some use for them eventually. (EKWB HDC 16mm OD fittings use M1.5x16 if anyone else is looking for the right size)

I bought these to install on my custom WASD mechanical keyboard to reduce clacking and stroke distance. I could have had WASD install them on my keyboard for $20+, or bought the o-rings from them without installation for $17+, but this seemed more economical.With the key remover that came with the keyboard, they were very easy to install. It only took me about 30 minutes to do my full sized keyboard. The only tricky part was removing and re-installing the brackets for the larger keys.This simple mod dramatically improved the feel of my already amazing Cherry MX Blue keys, and reduced the ridiculous amount of noise that they produce.

I do videography and duplicate and print my own DVDs. I was spreading the DVDs all over the place to dry until I bought these. They allow me to stack the DVDs on spindles and provide enough clearance for the DVDs ink to dry.

This is the perfect size o-ring for converting a preppy fountain pen from a cartridge to being an ink dropper pen where the barrel of the pen can be completely filled with ink. It is actually a slightly better fit for the Preppy fountain pen than the 010 Buna-N O-Ring, 70A Durometer, Black, 1/4" ID, 3/8" OD, 1/16" Width o-rings although both will work. Add a small dab of silicone grease to the threads and the converted pen will not leak ink at all. Very effective and inexpensive.

I needed a rubber washer to fix between a metal washer and the glass light fixture. The center of the washer needed to be 3/8". After searching in the washers, I came across these o-rings. They worked great and made better than the rubber washers..

These work well if you need a lot of stretch. They don't hold up to UV.

Used this for a MF135 hydraulic quadrant arm, and it fit well. Seems to be good quality.

Good quality 0-rings

as described
