Safety SF9000 PVC Flexible Round End Caps Shelf Organizer Tip Caps Wire Thread Protector Cover (inner diameter 8mm)

Finally found caps that fit 1/2" emt conduit. Why is it so hard? These fit perfectly. Could be thicker, but will do.

I bought these to be used as caps for partially used fountain pen ink cartridges. These rubber caps fit tightly over the open end of an ink cartridge when you are done with a cartridge but there is still ink in it; no waste of ink. Because there are different size ink cartridges I purchased both 6mm & 7mm size pouches of the caps. The size is based on the inner size of the cap and outer size of the ink cartridge, which is a better way to measure and use.

The size they advertised was large then reported. I re-ordered a small size. waiting for delivery

I think these are great. I bought a pack of 8mm caps to cover the ends of Hornady primer tubes which are supplied with the Hornady primer filler product. For some bizarre reason they come without an end, creating a risk of dumping the entire tube. Great solution for this problem and the 8mm size fits on easily and with enough resistance that there is little risk of dumping while not so great that its tough to remove. I modified several of my original Hornady primer pickup tubes to add to the two that come with the filler, works great there as well.

The mid-2000 version of the Bertha storm panel bolt consisted of a 1/4-20 threaded screw, a hex head and a 1/4" lag bolt (see my photos). These came with a white vinyl cap to protect the threaded part only. After so many years in the Florida sun these caps became brittle and very difficult to remove. They also did not protect the hex head. So after many years near salt water these heads started to corrode. A good portion of my house is now dark grey and I did not want to see a bunch white caps sticking out all over the place. Therefore I chose to use the Jocon black 10mm caps to cover both the threads and the hex head. Although their 9mm cap provided a slightly tighter fit around the hex head, the 9 mm cap is too short for these bolts. The 10 mm caps aren't quite as tight but I haven't had any fall off even in direct sunlight and 90+ temperatures. I also froze a few in my freezer and they stayed put. The inside length up to the tip is about 0.78".

I bought these to cover exposed rebar around our loop loc cover around our pool and the sizes aren't consistent...it could be the rebar but some were very snug which I wanted and some are just to big ...

Honestly used these for my rc cars nitro fuel bottles. These caps, since their always falling off .. might aswell get a nice supply that fits great and works well until my own human errors lol.work great. Otherwise expensive to just buy a set of two at actual rc websites etc. saves me money and I’m glad I purchased . And will keep purchasing when needed.

I don’t like them. I ordered the appropriate size but they were difficult to get on and I don’t think they’ll provide that much protection from injury if someone comes down on the rebar.
