Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For winterizing kits, safety means lead-free brass, a pressure gauge you can read and a valve that controls airflow; a kit that states none of those gets no safety points. 2 of the 5 kits state a warranty term, and 2 of the 5 state a 0-100 psi gauge. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EVOULTES RV Winterizing Kit | 9.7 | 32 | 22 | 21 | 7 | 3 |
| HFVSLFA RV Winterizing Kit | 9.7 | 30 | 21 | 21 | 7 | 3 |
| Gute RV Winterizing Kit | 9.6 | 29 | 21 | 21 | 6 | 0 |
| WINAMOO RV Winterizing Kit | 9.6 | 29 | 20 | 20 | 7 | 0 |
| Hohean Blowout Adapter | 9.5 | 27 | 20 | 19 | 6 | 0 |
The Solar Score runs on a 9.2 minimum and a 9.8 maximum, and the weighted point total is placed on that line in proportion, so more points can only raise it.
How to choose the best rv winterizing kit with blowout adapter
Start from hose length
The kits here state hose lengths from 16 inches to 17 inches: the Gute hose measures 16 inches, and the EVOULTES, WINAMOO and HFVSLFA hoses measure 17 inches. The Hohean kit states no hose, since it is an adapter only. A longer hose reaches tight spaces with less stress on pipes and fittings, so match the length to the space around your inlet. For the RV side, see our RV and Van Life guides.
| If you need | Look at |
|---|---|
| The longest hose | EVOULTES or HFVSLFA, 17 inches |
| A 0-100 psi gauge | EVOULTES or WINAMOO, 0-100 psi |
| A spare adapter | Gute, 2 adapters |
Gauge range
2 of the 5 kits state a 0-100 psi gauge, and 1 states a 0-60 psi gauge: the EVOULTES and WINAMOO gauges read 0-100 psi, and the HFVSLFA gauge reads 0-60 psi. A gauge lets you view the pressure value and adjust the airflow through the valve without running back to the air compressor. The Gute and Hohean kits state no gauge, so you watch the compressor instead. Pick the gauge range against the pressure your lines need, and never push past the stated max pressure of 300 PSI.
Shut-off valve and control
3 of the 5 kits state a shut-off valve: the EVOULTES, HFVSLFA and Gute kits let you adjust the airflow through the valve, and the Hohean adapter uses a ball valve for single person operation. A valve at the adapter means you control the blowout from the inlet instead of walking back to the compressor. The WINAMOO kit states no valve, so the compressor switch does the work. If you winterize alone, pick a kit with a valve you can reach.
Brass and lead-free
3 of the 5 kits state lead-free brass: the EVOULTES and WINAMOO metal parts are solid lead-free brass certified to less than 0.25% lead, and the Gute valve is solid lead-free brass. The HFVSLFA kit states brass fittings, and the Hohean adapter is heavy brass. Lead-free brass matters where the adapter meets drinking water lines, so check the material line before ordering. If the kit will also serve a sprinkler system, the female-to-female converter in the HFVSLFA kit covers that side.
Antifreeze or air only
These kits blow lines clear with air, and the listings frame that as a healthier and more environment friendly choice than antifreeze, which can contaminate the water supply. The EVOULTES kit works with RV antifreeze for full pipeline protection, while the Gute and HFVSLFA kits pitch air-only winterizing as the cleaner route. If your routine already uses antifreeze, pick a kit that states it works with it; if you want air only, any of the 5 kits blows lines clear with a compressor.
Sizing Notes
- Match the hose to the inlet: 17 inches on the EVOULTES, WINAMOO and HFVSLFA, 16 inches on the Gute, and no hose on the Hohean adapter.
- Match the gauge to the lines: 0-100 psi on the EVOULTES and WINAMOO, 0-60 psi on the HFVSLFA, and no gauge stated on the Gute and Hohean.
- Match the valve to the job: a shut-off valve on the EVOULTES, HFVSLFA and Gute, and a ball valve on the Hohean.
- Match the threads to the fittings: 3/4 inch garden hose threads on the EVOULTES, WINAMOO, HFVSLFA and Gute, and 1/4 to 1 inch MNPT and FNPT on the Hohean.
