Aprilaire arntf4 4 Inches Pvc Radon Transition Fitting Spigot X Socket Sch 40

Product Description

The Aprilaire ARNTF4 is a 4-inch PVC radon transition fitting designed for use in radon mitigation and HVAC drainage systems. Molded from UV-resistant white PVC, this fitting delivers a clean, professional look on any installation. The ARNTF4 uses a spigot x socket end style, making it compatible with standard Schedule 40 PVC pipe and fittings found on most residential and light commercial job sites. HVAC technicians and radon mitigation contractors rely on this type of transition fitting to simplify rough-in work and reduce the number of components needed at a single connection point. The ARNTF4 can replace anywhere from 2 to 5 individual fittings along with the primer and glue steps that go with each one, cutting labor time and reducing potential leak points in the system. This fitting is rated for Schedule 40 pipe, which meets standard pressure and flow requirements for radon vent stacks and condensate lines. When paired with the Aprilaire Condensate Bypass Kit, the molded internal slot on the ARNTF4 accepts the condensate weir for a precise, secure fit. This eliminates guesswork and keeps the condensate drainage path properly aligned. The fitting measures 10.75 inches in height and 8.43 inches in width, making it a compact solution that fits neatly in standard wall or ceiling chase openings. It can also be used as a stand-alone fitting without a fan cover, giving contractors flexibility on different job configurations. The white PVC construction resists UV degradation, so the fitting holds up in exposed indoor locations without yellowing or becoming brittle over time. This part is manufactured by Research Products Corporation under the Aprilaire brand and is engineered specifically to meet the dimensional and flow requirements of Aprilaire radon and HVAC systems.

Product Highlights
