Dorman 800-414HP HVAC Heater Hose Connector - Auxiliary Heater
Dorman 800-414HP Heater Hose Connector
Dorman 800-414HP is an OE FIX HVAC heater hose connector built for auxiliary heater applications on select Cadillac, Chevrolet, and GMC vehicles. It replaces the original plastic connector with a metal design that better resists heat and abrasion, helping address repeat failures in the heater hose and coolant hose connection.
Compatible With Cadillac Escalade, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and related full-size truck and SUV applications with an auxiliary heater setup.
Key Features
- Metal connector construction for improved durability over the factory plastic part
- Designed to match factory performance and fit on specified applications
- T-shaped heater hose connector with three ends for auxiliary heater routing
- Hose barb and quick disconnect end types for the original connection style
- Built to precise standards for a direct replacement on listed vehicles
- Part number 800-414HP for easy identification and ordering
Detailed Description
This HVAC heater hose connector is engineered for vehicles where the original connector can become brittle from heat and abrasion, then crack or leak at the hose connection. Dorman 800-414HP uses a sturdier metal construction while maintaining the OE-style layout needed for a proper repair. It is a direct-fit replacement for auxiliary heater applications on many Cadillac Escalade, Chevrolet Silverado, Tahoe, Suburban, Avalanche, and GMC Yukon models.
The connector features a T-shaped body, a hose barb end, and quick disconnect ends to match the factory routing. Its aluminum, plastic, and rubber material design supports the connection points used in the heater hose system. This part cross-references GM 15055342 for the same application.
What It Helps Fix
- Coolant seepage at a cracked heater hose connector
- Broken or brittle plastic connector ends
- Loose auxiliary heater hose connections
- Leaks caused by heat-related connector failure
- Repeat repairs from abrasion damage at the hose junction
Installation Notes and Tips
Verify the auxiliary heater hose routing, end sizes, and quick disconnect style before installation. Confirm vehicle year, make, model, and position against the fitment list for Cadillac Escalade, Chevrolet Tahoe, Chevrolet Suburban, and GMC Yukon applications. Inspect the surrounding heater hoses and seals for wear before transferring the new connector into service.
Quality Assurance
Dorman OE FIX parts are engineered to exceed the service life of the original plastic design while maintaining factory-style fit and function on specified vehicles. Part number 800-414HP is manufactured to precise standards for consistent replacement performance.
