What kind of adhesive is typically used for PVC conduit joints?

PVC cement specifically formulated for bonding PVC materials is the correct choice for adhesive used in PVC conduit joints. This type of cement contains a special formulation that not only bonds chemically with the PVC, creating a strong and durable joint, but also helps to fuse the surfaces together, ensuring that the connection can withstand the stresses of installation and use.

PVC cement is designed to soften the surfaces of the PVC pipes, making the bond incredibly strong once it cures. It is essential for creating watertight and secure joints that are critical in electrical and plumbing applications where PVC conduit is often utilized.

Other types of adhesives, such as general-purpose glue, epoxy resin, or silicone sealant, do not provide the same chemical bonding and physical properties needed for a reliable connection in PVC systems. General-purpose glue might not adhere properly to PVC or withstand environmental conditions, while epoxy resin may not offer the specific flexibility and compatibility required for PVC. Silicone sealant is more suited for sealing purposes rather than creating structural bonds, making it unsuitable for the durable and secure joints required in PVC conduit installations.
