Guarding 1″ PVC vent and condensate drains is easily accomplished with the SVC-IS1 cap. This cap features an 18 x 18 mesh 316 stainless steel screen for many years of reliable service. While the available open area of the SVC-IS1 is an impressive 70%, the .047″ openings are small enough to keep out many species of ants along with bees and wasps. Animals, such as mice and chipmunks, also are unable to enter a vent or drain guarded with this cap.

One inch PVC pipe has an outside diameter of 1.315″, which is just under 1-3/8″. The SVC-IS1 has a screened area of 1.049″, with the attaching end’s tapered 1.320″ inside diameter, for use with standard 1″ PVC pipe. The SVC-IS1 may be secured onto a 1″ PVC pipe termination with a cement weld, slip fit or with the included set screw.

Each SVC-IS1 vent and drain cap sold is individually boxed with instructions and a free hex wrench.

Please note: In following industry standards, PVC pipe and related fittings are sized according to their usable inside diameter. A straight PVC pipe termination measuring nearly 1″ on the outside diameter is consistent with 3/4″ pipe and would likely utilize the SVC-IS075.
