rubber butt cap

rubber butt cap

A rubber butt cap is what you would use if you wanted to adequately seal an end of a tubing or a similarly-shaped piece of equipment. For example, you would use a rubber butt cap if you wanted to seal the end of a fishing rod. Even though there are alternative solutions to rubber butt caps, such as cork butt caps, they are nowhere near the real deal as long as you use durability and performance as the main criteria for determining the quality. In a nutshell, a rubber butt cap will keep whatever it is that you decide to seal, from external influences such as humidity, dust, various impurities, etc. Additionally, this type is especially cherished for its longevity and increased resistance to physical influences, and enhanced friction.  

The only thing you need to take care of before ordering your rubber butt cap is to measure and determine the right size and shape so we could deliver precisely what you want. To select the right rubber butt cap, match its internal dimensions and depth to the component it covers. Include those dimensions and the required fit in your inquiry. Naturally, if the size and shape of the rubber butt cap you intend on buying does not comply with our standard offer, we are proud to inform you that we will gladly craft a customized solution to meet your needs. Just make sure you provide us with all the technicalities regarding a specific model and we will do our best to answer in record time. Besides that, you can also pick the color of your future rubber but cap, if the standard black does not satisfy you. We look forward to hearing from you and hope our products will deliver even more than you expect!
