Coyote 2″ Step-Down Hose Adapter (03-1894)

Description

Overview

The Coyote 03-1894 Step-Down Adapter makes it easy to join two different hose diameters while maintaining proper airflow.
Because it features a gradual taper, air moves through the connection smoothly without backpressure.
This fitting helps technicians adapt various hose sizes during OEM builds or field retrofits.

Function and Performance

This step-down adapter transitions from a 2-inch inlet to a slightly smaller outlet size.
The tapered interior reduces flow resistance, keeping the HVAC system quiet and efficient.
As a result, it provides balanced airflow even when connecting hoses of unequal size.
In addition, the snug friction-fit design minimizes air leakage and vibration.

Durability and Design

Coyote molds the 03-1894 adapter from heat- and UV-resistant ABS plastic for strength and long service life.
Because the material maintains its shape under temperature and vibration, it performs reliably in harsh duty cycles.
The smooth, seamless construction eliminates weak points and makes installation easier.

Installation

Installation is quick and simple.
Attach the larger 2″ hose to one end and connect the smaller hose or fitting to the other.
The precision-molded taper provides a secure friction fit that can be reinforced with a clamp if desired.
No special tools or adhesives are required.

Applications

The Coyote 03-1894 2″ Step-Down Hose Adapter is used in buses, RVs, construction machinery, ag equipment, and industrial HVAC systems.
It’s ideal for connecting different duct or vent sizes, especially in compact dash panels or custom installations.
