Coyote 2½″ Hose Adapter with Flange (03-1809)

Description

Overview

The Coyote 03-1809 Hose Adapter with Flange lets you mount a 2½″ hose connection directly to a panel or duct wall.
Because the flange spreads load across the surface, it keeps the hose joint stable under vibration.
This design gives the installation a clean, finished look while protecting the panel opening from stress and wear.

Function and Performance

This 2½-inch adapter connects flexible hose to plenums, manifolds, or sheet-metal panels.
Air flows through a smooth, round bore, so pressure drop and noise stay low.
As a result, the HVAC system maintains steady airflow and consistent performance.
In addition, the flange face helps prevent movement, which reduces the chance of leaks over time.

Durability and Design

Coyote molds the 03-1809 adapter from impact-resistant black ABS, which stands up well to heat, UV, and vibration.
Because the wall thickness is consistent, the part resists cracking and deformation even in tough service.
The flange includes four mounting holes, allowing secure attachment with screws or rivets.

Installation

Installation is quick and straightforward.
Place the flanged adapter into the panel cutout, align the holes, and fasten it in place.
Then slide the 2½″ flex hose over the adapter spigot and secure it with a clamp or tie.
This method creates a stable, rattle-free connection that is easy to service later.
