200 Pieces Rubber End Caps Assortment Kit Vinyl Flexible Bolt Screw Rubber Caps Thread Protector End Safety Cover Multi-Purpose,9 Sizes Form 2/25" to 4/5" (Red & Black)

Purchased for may little shop to add a little more quality to my projects. The value for what they are used for is good. Quality is good for the cost of this assortment. Performance is good for a rubber cap, as I use them as appearance, and safety for my customers on sharp or protruding bolts and rods. The fit is good on most applications, but they appear to be sized metric which is OK on my newer projects and repairs.

Great product at great price. Very handy to have around the shop

I received the full size assortment of caps, but unlike the description, they are red only - no black. For my purposes, I would like to have black caps for some things, but it's not a real issue. However, it would matter if you intend to use these for electrical cable or terminal identification. I would give five stars if the product matched the description.

These work good for me on my pcp fill port & air compressor too. Easy to find the right fit. I should have bought this multi size pack for my Umarex Gauntlet pcp

Will buy again! I use them for everything to brake bleeding covers to vacuum caps to bolt protection!

Every size nipple for every job big and small. Fit where I needed them to. Unless it's hot and under pressure. Then they don't do so well. But other than that, not bad... Thank you.

Not actually for vacuum lines or ports but have used these plenty of times just for that. I like having these around to protect tube ends, orifices, fittings, threads etc. good for stopping leaks when removing a part. Have used to protect fittings and openings when sand blasting, painting, or cleaning. These may be listed as a certain size but are fairly flexible. One size will adapt to a lot of shapes and sizes.

good product
