The Webasto Isotemp Hot Water Heater doesn't come with the hose, fittings, or hardware needed to complete installation — this kit fills that gap with everything required in one box, saving you the hassle of sourcing parts across multiple retailers. All components are made from brass or stainless steel for long-term rust protection, and the kit is properly sized for a direct fit on Sprinter, Transit, and Promaster van conversions.
Kit Includes:
- 50 ft Gates Heater Hose (5/8" ID)
- Brass fittings — 2x 5/8" barb tee, 2x 5/8" barb to 1/2" female thread, 2x 5/8" 90° elbow, 2x 3/4" PEX valve
- Hardware — 12x stainless hose clamps (#10), 12x 1/4" x 1" stainless self-tapping hex screws, 10x stainless zip ties
Compatibility:
- Fits Sprinter, Transit, and Promaster vans
