Coyote Flexible Heater Hose Protector (03-1830)

Description

Overview

The Coyote 03-1830 Heater Hose Protector provides lasting protection wherever a heater or coolant line passes through a panel.
Because the grommet flexes, it forms a tight, vibration-resistant seal around the hose while absorbing movement.
This reduces the chance of leaks and prevents chafing at the pass-through opening.

Function and Performance

This flexible grommet protector lines the panel hole, creating a soft barrier between the metal edge and the hose surface.
As a result, the hose stays centered and protected even under vibration or thermal expansion.
In addition, the grommet helps maintain airflow and coolant integrity by preventing abrasion damage that can lead to failure over time.

Durability and Design

Coyote molds the 03-1830 from high-grade flexible rubber formulated for temperature and chemical resistance.
Because it resists cracking, heat, and oil exposure, it performs reliably in demanding HVAC and coolant environments.
The rounded edge design ensures a smooth surface that won’t cut or pinch hoses during operation.

Installation

Installation is quick and tool-free.
Press the protector grommet into the panel hole until the flange seats flush.
Then slide the heater hose through the center opening.
The flexible rubber grips the hose and the panel, holding everything securely in place.

Applications

The Coyote 03-1830 Flexible Heater Hose Protector is used in buses, RVs, trucks, agricultural and construction equipment, and industrial HVAC systems.
It’s ideal for bulkhead or firewall pass-throughs, cab penetrations, and metal panel edges where hose protection is critical.
