End caps are commonly used at the end of the tubing and serve as a cover for insulated pipe fittings in an insulation system. They are most commonly made of polyvinyl chloride and also resin, stabilizers, lubricants, etc., which are hot-pressed to extrude. These caps are durable, impact resistant, have a long operational life, and are easy to install. Applications that have a service temperature ranging from 0°F to 150°F use PVC caps because they are cost-effective to use. These are known as the first plastic material to be applied and developed. The many benefits provided by these end caps, like corrosion resistance, low price, easy bonding, and hard texture, make them a popular choice to be used for pipe or tube fittings.
However, due to reasons like seepage additives and PVC monomer, the end caps are only appropriate for water supply systems whose temperature does not exceed 45°C.
Things to Consider When Purchasing End Caps
There are a few things that need to be considered before purchasing end caps, more specifically PVC end caps. Follow the following steps to make it easy for yourself:
- First, you need to pay close attention to the surface finish and the whiteness.
- Then select one and do a drop test on it. The ones that break easily are usually products that are high in calcium. Therefore, it is very important for the pipes to meet your requirements when they are being sold for the right prices.
- The last test you can do is to step off the end cap with your foot to see if it cracks or elongates.
- At the end of such tests, you will find out whether the product that you considered purchasing is suitable for your application or not, and it will also determine the durability of the product.
- These caps come in different colours and sizes. The common colours are black and white. End caps are also available in a wide variety of sizes; therefore, you need to make sure that the capsize is compatible with the pipe size so that it can easily fit onto the ends of the pipe.
How to Install an End Cap?
To connect the end caps to the pipe, you simply need to follow two steps:
- Insert the end of a PVC pipe within the port on the external end cap.
- Then you need to push and make sure that the pipe is fully seated into the interior of the cap.
What Are End Caps Used For?
Endcaps are mostly made of PVC, stabilizers, and lubricants and are used to seal the endings of a PVC pipeline in an insulation system. They are usually installed at both ends of the PVC pipe to seal the pipe fittings at both ends of the pipe. End caps can be of two types that are insert type and thread type. There are professional end caps available in the market that can be utilized efficiently for this purpose. Make sure that you purchase products made from high-quality raw materials. When the product is high quality for PVC end caps, the inner wall is polished so that it can prevent water leakage, clogging, and unobstructed drainage.
