There are many different types of plastic 4x4 available on the market, each designed for a specific purpose. Below is a list of the most popular types of plastic 4x4, along with a brief description of each.

1. traditional plastic 4x4 - This type of plastic 4x4 is the most basic and simplest design. It consists of a tube that fits over your head and extends down into your mouth. There is no valve or purge system, so it is important to blow any water out before taking a breath.
2. dry top plastic 4x4 - This type of plastic 4x4 has a valve at the top of the tube that prevents water from entering. A dry top plastic 4x4 is ideal for swimming in rougher conditions or waves, as it will keep your breathing tube dry even if water does splash over the top.
3. semi-dry top plastic 4x4 - This type of plastic 4x4 has a valve at the top of the tube, but also has an additional hole near the mouthpiece that allows water to drain out. Semi-dry top plastic 4x4 are a good compromise between traditional and dry top models and are great for swimming in moderate waves or chop.
4. purge plastic 4x4 - Purge plastic 4x4 have a valve at the bottom of the tube, near the mouthpiece, that allows water to be purged easily from the tube. These are ideal for beginner or occasional plastic 4x4 ers. There are many features and benefits to using a plastic 4x4 while diving or swimming.

Swimmers and divers can use a plastic 4x4 to move through the water more quietly and can avoid disturbing aquatic life when diving in areas where there are regulations restricting surface diving noise.
