Schedule 80 PVC Fittings

Schedule 80 PVC fittings, also know as Polyvinyl Chloride, are used for many applications. Application uses are industrial irrigation, water treatment plants and chemical facilities. With its excellent rigidity and chemical resistant properties, Schedule 80 PVC can be used for many chemical related areas. Schedule 80 fittings are made with thicker walls for higher pressure applications. Schedule 80 fittings adhere to ASTM D-2467 Standards. Schedule 80 pressure fittings range from sizes 1/4” to 14” and pressures will vary due to fitting size. For jobs that require sizes larger than 14” those fittings are fabricated and are made for lower pressure applications. Schedule 80 fittings are manufactured up through 24”. Schedule 80 PVC fittings can handle up to 140 degrees F and can be used in a wide range of applications that may include very corrosive media. Most fittings are offered either socket or threaded. It is recommended to use a strong, sturdy primer and cement when installing schedule 80 pressure fittings with socket ends. Use a good thread tape if you prefer to use threaded fittings. A strong clean connection will reduce the chances of failure in the PVC system. Our schedule 80 fittings are NSF 61 certified and listed for potable water service.

Schedule 80 PVC fittings are used to connect pipes, other fittings, or equipment to form a complete plumbing network for the safe transfer of liquid media such as water, chemicals, solutions, and ingredients. Pipe fittings are a core component in the installation and operation of pipelines as they allow connections and directional changes to be made between different plumbing sections and equipment. Schedule 80 PVC fittings are also known as heavy duty or industrial PVC fittings. They are made to Schedule 80 standards, which means the fittings have thicker pipe walls compared to Schedule 40 fittings, for use with Schedule 80 pipe. The extra pipe thickness of Schedule 80 PVC fittings provides improved physical durability, pressure rating, and chemical resistance. Heavy duty pipe fittings are commonly used in applications such as potable water distribution, irrigation systems, chemical distribution, industrial and manufacturing supply lines, agriculture, commercial developments, as well as public and recreational water features such as pools, spas, and water parks.

Our USA made Schedule 80 PVC fittings are engineered and fabricated by the industry’s top leading manufacturers to ensure lasting performance, reliability, and quality. Our Schedule 80 pipe fittings are tested, rated, and certified to handle the approved range of operating conditions for PVC compatible liquids such as water, chemicals, mixtures, ingredients, and material solutions.

Chemical Applications

Schedule 80 PVC fittings are naturally resistant to many commonly used chemicals and fluids. This makes them an excellent option for handling work materials and conditions involving various chemical solutions and corrosive media. The thicker sidewalls of Sch 80 pipe fittings make them better suited for hard working applications requiring higher liquid pressures and chemicals. Common chemicals used with Sch 80 PVC fittings include bleach (sodium hypochlorite), alcohols, deionized water, hydrochloric acid, and sodium hydroxide. Chemical compatibility should always be considered and verified before installing and using PVC pipe and fittings for chemical applications.

Recommended Installation Practices

Schedule 80 PVC pipe fittings should be installed using proper techniques and recommended practices. When installing Sch 80 socket fittings, it is recommended to use a strong primer and cement, applied per directions, for a secure, watertight seal. This is also known as solvent weld and pipe glue. When installing Sch 80 thread fittings, it is recommended to use high quality pipe tape to prevent leaks. The right connection practices will minimize the potential for leaks or system failure over time.
