Plastic Hose Fittings

There are very many types of plastic hose fittings. These fittings are made using a common plastic called Polyethylene. The most common plastic hose fittings include; reducer nipples, adapters, connectors, elbows and tees. Below is a more in-depth discussion on these fittings.

1. Reducer nipples
Reducer nipples are usually sold as black hose fittings. They are made from a linear Polyethylene that has high molecular weight. Reducer nipples are made to withstand high impact and chemical corrosion. They are also designed to function at low temperature ranges between -65 and 190 degrees Fahrenheit. It is important to note that common plastic reducer nipples can withstand 125 PS1 when fitted using appropriate clamps. Reducer nipples are also NSF 61 listed and UV resistant. They are sold in NPT x NPT sizes.

2. Adapters
Adapters are also common plastic hose fittings. As the name suggests, adapters are designed to fit into hoses using their long narrow tip. Like reducer nipples, adapters are also made from a linear Polyethylene that has high molecular weight. Adapters are also designed to withstand chemical corrosion and high impact at low temperatures ranging between -65 and 190 degrees Fahrenheit. It is however important to note that you can get customized designs with any kind of capabilities. Common plastic hose adapters can handle pressures of up to 125 PSI. Their sizes are listed as NPT X Hose ID.

3. Connectors
Connectors are also among the common plastic hose fittings. Connectors simply connect one hose to another. They are usually used when connecting short hoses together to make one long hose. It is important to note that there are different types of plastic hose connectors capable of connecting two hoses together of varying sizes. Like adapters and reducer nipples, connectors are also made from linear Polyethylene that has high molecular weight. Connectors are also designed to withstand high impact and chemical corrosion at low temperatures. The most common types of connectors also have a maximum PSI of 125 and a temperature range between -65 and 190 degrees Fahrenheit. Connector sizes are indicated as HOSE ID X HOSE ID.

4. Elbows
Elbows are black plastic hose fitting made using linear Polyethylene that has high molecular weight. As the name suggests, elbows resemble the human elbow i.e. they are curved forming a ”C like” shape. Elbows are simply special connectors used to connect one hose to another in a corner junction. Like all the other plastic hose fittings, elbows are also designed to withstand chemical corrosion and high impact at low temperatures. Elbows function optimally in temperatures ranging from -65 and 190 degrees Fahrenheit. They also have a maximum PSI of 125 when fitted with appropriate clamps. Elbow sizes are usually indicated using HOSE ID.

5. Tees
Tees as the name suggests are plastic hose fittings which assume a ”T” shape. The fittings are used to connect more than two hoses together forming what is popularly known as a T junction. In regards to size, Tees are usually indicated as NPT X Hose ID. Common plastic Tees also have a maximum PSI of 125 and a temperature range between -65 and 190 degrees Fahrenheit.
