Commonly Asked Questions

Q: What are some “Best practices” for installing Schedule 80 PVC fittings with socket (solvent) end connections?

A: When installing Schedule 80 PVC fittings it is important that both the fitting and pipe are clean and free from dust, dirt, or other residue.  Wiping the inside walls of the fitting and outside of the pipe with a dry or slightly damp rag should sufficiently clean away most substances that could impede a proper connection. 

We recommend first applying sufficient quantities of PVC Primer to prepare the pipe and fitting.  Allow the primer to react with the PVC which generally takes only a few moments.  PVC glue should then be applied to both the inside of the fitting and the outside of the pipe before sliding the two together. 

When both parts have been prepared with primer and glue, slide the fitting and pipe together.  Apply consistent pressure so that the pipe fully enters the fitting.  Continue applying pressure for several seconds or even minutes to ensure the bonding agent can properly react and seal the fitting together with the pipe.  In some situations PVC fittings can have a tendency to slide backwards if the bonding agent has not been given enough time to cure and pressure is no longer being exerted in the opposing direction.

Different bonding agents, PVC Glues, and PVC Primers are recommended for installations involving rigid PVC pipe or flexible PVC pipe.  We have solutions for both applications, please contact us if you are unsure which product is best for your specific installation.

Q: What is SCHEDULE?  Is this fitting Schedule 40 or Schedule 80?

A: Schedule 40 and Schedule 80 are measures of wall thickness for PIPE and FITTINGS.  Different Schedules means different wall thicknesses, pressure ratings, applications & usage, and color.  RedFlag Products manufactures WHITE Schedule 40 fittings and GRAY Schedule 80 fittings in line with industry standards.

Q: What is the difference between Socket and Threaded end connections?

A: Socket end connections have a smooth inner wall that will slip onto pipe of the same size:.  Also known as Slip or Solvent end connections, this version of fitting should be used with a recommended PVC glue and primer to ensure a watertight, leak-free installation.

Threaded end connections have a threaded inner wall that will twist onto threaded pipe.  Threaded seal tape should be used to ensure a watertight and leak-free installation rather than PVC glue or primer. 

For installations that will not be changed or taken apart at a later time socket end connections are generally preferable as all parts in the system are bonded together through the application of glue and primer.  Should the installation be temporary or if changes will be made at a later time, threaded parts may be preferred due to their ability to disassemble and amend without increased construction costs, cutting out of pipe, fittings, and valves, or need for PVC glue and primer.

Q: What are some of the chemical resistance advantages of using PVC over other plastics and materials?

A: PVC material is exceptionally inert and offers excellent resistance to a broad range of reagents and mixtures that are corrosive to many other materials.  Resistance to moisture and oxidation make PVC useful in indoor as well as outdoor, and chemical processing applications.  PVC is generally inert to most mineral acids, bases, salts and paraffinic hydrocarbon solutions.

In addition to temperature and reagent concentration, other factors such as stress level and product quality can also affect the chemical resistance of a plastic material and must be given proper consideration when making specification selections.  Therefore, the final determination of suitability must often depend on some in-service testing which should be done with appropriate care and safety precautions.  Should you have questions regarding specific uses of RedFlag products please contact our technical department.

Q: Can PVC fittings be used with compressed air or gas?

A: RedFlag Products DOES NOT RECOMMEND using any of our thermoplastic valves, fittings, or pipe with systems that transport or store compressed air or gases, neither for use in above nor below ground applications.  The use of RedFlag Products, Inc. thermoplastic parts in compressed air or gas systems automatically voids any warranty for the part, is against our recommended usage, and is entirely the liability and responsibility of the installer.

Warning: DO NOT use compressed air or gas in conjunction with any thermoplastic pipe, fitting, valve, or other product manufactured or sold by RedFlag Products, Inc.  DO NOT test, clear systems, or experiment with any thermoplastic products or parts and compressed air or gas.  USE OF COMPRESSED AIR OR GAS AND THERMOPLASTIC PIPING SYSTEMS MAY CAUSE EXPLOSIVE FRAGMENTATION AND LEAD TO SERIOUS OR FATAL BODILY INJURY.
