What’s Pipe Glue?

Pipe glue is used to create watertight connections between PVC pipes. It is important to work in a well-ventilated space and wear a respirator to avoid inhaling fumes. The glue should be applied evenly and allowed to cure before use. Staff at hardware stores can help select the appropriate glue.

Pipe glue is a product for creating watertight connections between lengths of pipe, usually polyvinyl chloride (PVC) piping. Metal tubing is typically joined by welding or the use of epoxies rather than glues. Many hardware stores sell tube glue, often offering different types for different types of projects. People should be careful when working with this substance, because dangerous fumes can be released during work that can make people ill, especially in confined areas such as crawl spaces under houses.

When people connect PVC piping, they start with a cleanly cut piece of plastic and apply primer to soften the plastic, followed by pipe glue. Then, they may fit two pieces of pipe together or connect the pipe to another type of fitting. The tube is held in place to allow the glue to set, and once it has fully dried, the connection should be watertight. Water or other materials transported in the pipe do not flow out, and the material in the surrounding environment such as air does not enter the pipes.

Companies design pipe glue to hold plastic together tightly for years or decades, reducing the amount of maintenance needed. It’s also non-corrosive and shouldn’t damage or eat into the plastic. Other types of glues can cause pitting and other problems, leading to leaks and an eventual joint failure. Typically, people notice a strong odor when priming and gluing PVC. Wearing a respirator is recommended to avoid inhaling fumes directly, and working in a well-ventilated space to reduce the risk of injury.

People can paint or spray tube glue on a tube, depending on the product and their needs. It is important to apply an even layer and avoid making it too thin or too thick. The product should come with clear directions giving information on how much glue to apply and how long the joint needs to cure before water can be run through the pipes. If people stress the joint by bumping into it or using plumbing before the glue sets, it could crack.

If people aren’t sure what type of pipe glue to use, they can consult a staff member at a hardware store. The staff are familiar with all the products the stores offer and can help customers select the most appropriate supply for their needs. Plumbers and contractors can also provide information, including advice on installing piping in accordance with building codes.
