## Description

E-CAP321 Thermoplastic Vent Cap for Furnace Flue PVC Pipe | Half-Sphere GELOY CR7520 Resin Cover | Keep Small Animals Out of Exterior Vent Outlets | Exhaust Cap Fits PVC Flue Pipes 1.5",2",&3"

## Features

- E-CAP321 Thermoplastic Vent Cap for PVC and ABS Vent Pipes: The E-Cap is a hemispherical thermoplastic cover that can be easily installed over the open end of a high-efficiency gas furnace PVC or ABS flue pipe. Exterminators everywhere are installing E-Caps to protect PVC and ABS vent and flue pipes from debris and small animals such as birds, squirrels, rodents, tree frogs, and even snakes!
- High Quality GELOY Resin: The constant exposure to different weather conditions, UV light, heat, and chemicals from furnace gases requires a material with high resilience. To ensure that our innovative heater exhaust vent cover offers the highest level of weather resistance and durability, we chose GELOY CR7520 acrylic-styrene-acrylonitrile (ASA) resin. This material gives the E-Cap high resistance to oxidative degradation and an attractive glossy appearance. It has excellent weatherability, good flow/aesthetics and high impact.
- E-Cap Benefits: Our vent duct flue cap is proven to keep flying debris and small animals from creeping down exterior vents while also improving air flow up and down each protected exhaust vent or PVC flue pipe. It also eliminates excessive moisture that can rust or ruin high-efficiency gas furnaces, tank-less hot water tanks, plumbing, and other PVC-vented installations.
- Thermoplastic(Geloy Resin) Vent Cap: Featuring a faster and easier installation than P-trap vents, this E-cap precisely and quickly fits 1.5", 2", and 3" PVC pipes with standard PVC glue. It's perfect for either vertical or horizontal flue pipe installations and can be used on all PVC-vented high-efficiency applications such as HVAC exhausts and intakes. It also works for plumbing, radon gas vents, and high-efficiency tankless water heaters.
- Vent Pipe Cover Offers: The E-CAP321 features superior design, function, and cost-effectiveness in comparison to other conventional outside vent covers. It's resistant to heat, cold, precipitation, and UV radiation. It reliably protects your furnace motor and interior from damage due to moisture and debris, never freezing up from condensation, and promotes unrestricted air flow of both the intake and vent flue.
