Customers say

Customers have expressed positive opinions about the quality, fit, and value of the engine component cap. They mention that it's made from quality plastic and holds up well. Some appreciate the value for money, saying that it’s a really cheap insurance against having a fitting coated in who knows. That said, opinions are mixed on the material.

Inexpensive alternative for air tool dust caps

Inexpensive alternative for air tool dust caps
I wanted to to buy dust caps to protect my air tool connectors. Most were priced about $3.50 apiece. These rubber caps are flexible enough fit my 1/4 npt air tools with a little stretching. They are thick and seem to provide good protection. At 25 units for under $10, you won't break the bank.

I used these to replace a plastic type of cover. Those were more rigid and would not stretch to fit. These are a softer, rubber-like material that fit more tightly and don't split.

Nice quality, I will never need another brake bleed valve cover again. For people like me that are really into old cars this is a great product. While working on my antique auto I noticed that I needed a couple of this things. Sure you can buy a package of 2 or 4 but they are very expensive per item. This way you get all you need and can even have enough to give some to your like-minded friends. Don't know about others but our group gets together to work on our cars we all bring items to keep our main sponsor's garage stocked and spread around the cost of those little items that can eat you up. This product is great for me and our little group, they made fun of me for buying them (nobody will ever see them but I know my car's brake are 100%) but I noticed some other people grabbing them and putting them on their cars also.

I am using these on zerk fittings below the water line on the transom assembly of my offshore performance boat. The old zerk covers were lost at sea, and so were the first replacements I tried (different product than these). I figured, why not give another brand a shot, and these are working great. They survived and remained in place on a trip from south Florida to the Exumas (outer Bahamas) and back at speeds averaging 50 knots and several instances of pretty snotty water conditions. I would not have even blamed these things if they had come off under the circumstances, but to my amazement they were still in place when we hauled the boat after the trip.

1.0 out of 5 stars Utter Excrement! Do not waste your money!!
Reviewed in the United States on September 6, 2022

Purchased October 2021. Installed on November 23, 2021. Vehicle has been essentially unused since.... total of about 250 miles in 9 months and some days. Today I inspected them all as I am going to bleed/flush brakes and lube the front end. I HAD a total of 13 mounted (4 brake, 9 front end).

EVERY SINGLE ONE is now non-functional or missing....

The rubber is cheap Chinese crap that deteriorated to nothing in 9 months. In the shade.... No sun at all...

Makes me so mad....

Does ANYONE in the USA make a similar product? I'll pay more. I just want a NON-Chinese CRAP product.

4.0 out of 5 stars Soft pliable rubber to snugly fit
Reviewed in Canada on January 22, 2022
Verified Purchase
Soft enough to fit snug over grease or brake nipples. Has a built in ridge on the inside to better grab onto nipple. The retaining ring is nice touch. If you dont want this retainer for certain nipples, just cut off. I reccomend these as opposed to the others without retainer because you can easily cut off if not needed.
