Description

Premium Upgrade:Unlike the original plastic(OE) coolant connector that cracks from constant engine heat and vibration, this heater core hose connector is machined from solid stainless steel. Designed to endure extreme under-hood temperatures, resist corrosion, and eliminate brittle failure.

Direct Fit Replacement:Built with precise 3/4″ inlet/outlet tube x 5/8″ hose barb sizing, this 800409 coolant connector matches the OE form and dimensions for hassle-free installation. Use a heater hose disconnect tool for removal; lubricate the heater core tube with soapy water before sliding on new connector until you hear an audible “click”.

Wide Compatibility:Replaces OEM part numbers: 800409, 15032062, 15151873, 15151875, 15792820, 15792821, 15792822, 15834772, 15834773. Compatible with select Chevrolet Silverado / Tahoe / Suburban / Avalanche / Express, GMC Sierra / Yukon / Savana, Cadillac Escalade, Buick Rainier (1998–2014). Check fitment tool below for your specific year/make/model.

Plastic Factory Defect Solution:Factory plastic connectors are prone to heat fatigue, leading to hairline cracks, coolant loss, and overheating. This upgraded stainless steel version eliminates that common failure point—giving you peace of mind on long hauls and towing.

Hassle-Free Upgrade & Pack Of 2:Includes two connectors—ideal for replacing both the inlet and outlet on your heater core. Direct bolt-on replacement requires basic hand tools; simply remove your disintegrated factory connector and slide this durable upgrade in place.

1 Year of Easy-to-Reach Support:We offer 1 year of friendly, accessible support. If you have any questions, just let us know.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for MATICVAS products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
