The SVC-IS15 is a multi-use 1-1/2″ PVC vent cap that is designed to protect ventilation pipes from debris, insects and rodents. By maintaining a 70% open area, the SVC-IS15 allows ample air, gas or water to pass through while keeping out even small ants and mosquitoes. Because of its versatility, this vent cap may be used in a variety of industries including agriculture, plumbing, HVAC and even in recreation (boats, pools, recreation vehicles, etc.).

The premium 316 stainless steel screen used in the SVC-IS15 is designed to provide both durable and extensive filtration for many years. 316 stainless steel offers superior resistance to corrosion in many different environments including acidic environments and salt water. Openings of .047″ ensure that both large animals and small bugs will not pass beyond the screen.

Installation of the SVC-IS15 vent cap accommodates many different applications and may be securely installed without the need of any power tools. This vent cap may be installed with a snug slip fit, with the included fasteners for a secure but serviceable installation or cement welded for a permanent installation. Since the hex screws in this cap are also made of stainless steel, no unsightly corrosion stains will appear on or around the cap, and a free hex wrench ships with each cap.

The inside diameter of the SVC-IS15 measures 1.910″ and is designed to fit snug and directly over standard 1-1/2″ DWV PVC pipe vent and low pressure drainage terminations with an operating temperature that meets ASTM D2665 standards. For 1-1/2″ high pressure discharge pipes, including those used for sump pumps, the SVC-RS15 should be used instead. Please note that schedule 40 and schedule 80 1.5″ PVC pipe has an outside diameter of 1.900″, which this screened vent cap is designed to fit over.
