WINAMOO RV Winterizing Kit — 17in Brass Blowout Adapter with 0–100 PSI Gauge, 3/4" GHT Quick-Connect

WINAMOO Dual Purpose RV Winterizing Kit is a metal brass blowout adapter set with a 17" hose, pressure gauge, and 3/4" GHT quick-connect fittings to safely clear water from RVs, trailers, hoses and irrigation lines.

This compact kit combines heavy-duty brass fittings, a visible 0–100 psi gauge and a flexible hose to let you attach an air line to water connections for blowout winterization and maintenance. Built for tight spaces and repeated seasonal use, the assembly links standard 1/4" air quick plugs with 3/4" garden-hose threads so you can evacuate water from RV plumbing, sprinklers or outdoor spigots without swapping adapters.

How does the WINAMOO kit help when preparing an RV for winter?

The kit lets you introduce compressed air at a safe, visible pressure to push water out of tanks, pipes and fixtures before freezing temperatures arrive. The pressure gauge lets you monitor psi so you avoid over-pressurizing delicate components.

• Brass male and female 3/4" GHT adapters for secure hose connections.
• 0–100 psi pressure gauge for real-time monitoring.
• 10.4" flexible hose plus 17" overall blowout reach to access tight spigots.
• 1/4" male quick plug to connect common air compressors or blowout kits.

Can I use this adapter on sprinkler and outdoor irrigation systems?

Yes. The male-thread plug is designed for RVs but can be combined with a simple female-to-female garden-hose converter to adapt to sprinkler valves and yard plumbing. That lets you clear lines and heads without introducing water-damaging freeze risk.

• Screw-on compatibility with standard garden-hose threads for easy converters.
• Sturdy lead-free brass construction resists corrosion in outdoor use.
• Flexible rubber hose reduces stress at fittings during angled connections.
• Sealing tape included to help ensure airtight connections when needed.

How durable and safe are the materials and fittings?

All metal components are lead-free brass rated under 0.25% lead, for long-term corrosion resistance and safer potable-water contact. The hose is a durable, flexible rubber designed to withstand repeated compression cycles and the mechanical strain of angled installs.

• Solid lead-free brass body for lasting performance and reliability.
• Flexible rubber hose engineered to resist kinking and corrosion.
• Clear, readable 0–100 psi gauge mounted for quick pressure checks.
• Threaded GHT fittings sized to fit standard garden-hose and RV spigots.

What’s included and how do I set it up?

The kit ships with the quick-plug blowout assembly, a female 3/4" GHT adapter and sealing tape so you can form a tight, leak-minimized joint. Setup simply involves screwing the GHT adapter into the water outlet, attaching the hose assembly, applying tape where needed, and connecting an air source with a controlled PSI range.

• 1 x 1/4" male quick plug attached to a 10.4" flexible hose with blowout tip.
• 1 x 3/4" GHT female adapter to mate with garden-hose style spigots.
• 1 x roll of sealing tape for secure threaded connections.
• Pressure gauge already mounted for immediate use and monitoring.

Who is this for? If you own an RV, camper, travel trailer, motorhome, boat, or maintain outdoor irrigation, this WINAMOO winterizing kit is built for DIYers and service pros who need a compact, reliable way to purge water from plumbing before freeze conditions. It’s especially useful for anyone who wants a visible pressure readout, sturdy lead-free brass parts and a flexible hose to reach awkward spigots without stressing fittings. Use it seasonally to protect plumbing and irrigation systems, or when performing routine maintenance and winter storage preparations.
