Coyote 2½″ 90 Degree Louver Adapter (03-1814)

Description

Overview

The Coyote 03-1814 Louver Adapter allows HVAC airflow to turn a 90° corner without losing pressure or efficiency.
Because it fits standard 2½″ flexible hose and louver connections, it’s widely used in compact HVAC systems.
The curved internal design prevents turbulence while maintaining steady airflow through the bend.
In addition, its molded construction ensures strength and long-term performance in demanding environments.

Function and Performance

This 2½″ 90 Degree Louver Adapter channels air smoothly around corners where straight ducting won’t fit.
The curved inner wall minimizes drag and noise, improving system airflow balance.
As a result, it supports efficient heating or cooling even in restricted or curved panel layouts.
In addition, the adapter’s precise fit ensures a tight seal for leak-free operation.

Durability and Design

Coyote molds the 03-1814 from impact-resistant black ABS plastic engineered to withstand vibration, heat, and UV exposure.
Because it’s a one-piece molded adapter, it stays rigid and sealed under load.
The satin finish provides a professional OEM-grade appearance that complements other Coyote HVAC components.
In addition, the lightweight design simplifies handling and installation.

Installation

Installation is fast and straightforward.
Attach the 2½″ flexible hose to each end of the adapter using clamps or zip ties.
Position the 90° bend in the desired orientation to route air around panels or other components.
Because of its universal sizing, it connects easily to standard louvers, diffusers, and duct fittings.
In addition, the compact bend radius allows use in confined HVAC housings.

Applications

The Coyote 03-1814 Louver Adapter is used in buses, RVs, trucks, off-road machinery, and industrial HVAC systems.
It’s ideal for tight dashboard spaces, floor ducts, and wall-mounted HVAC enclosures where a 90° connection is required.
Because of its versatility and durability, it’s also popular in OEM HVAC builds and retrofit installations.
