EVOULTES Brass RV Winterizing Kit with Schrader Valve Plug — Lead-Free Brass, 17" 300 PSI Hose

EVOULTES Brass RV Winterizing Kit is a lead-free all-brass adapter set with a Schrader valve plug and shut-off that lets you safely blow out and winterize RV water lines.

Designed for RV owners and technicians, this compact kit combines brass fittings, a durable rubber blow hose, and a Schrader valve adapter so you can clear water from plumbing lines before freezing weather arrives. The components are rated for high pressure and extreme temperatures, and the assembly works with standard garden hose threads and an air quick-connect for fast attachment. Included Teflon tape and a shut-off make leak prevention and controlled air flow straightforward for seasonal maintenance.

How does this kit remove water from an RV plumbing system?

The kit lets you push compressed air into your water lines via a Schrader valve adaptor and designed hose, forcing residual water out of pipes, fittings and fixtures. The brass shut-off valve gives you control over airflow so you can cycle through fixtures without constantly reconnecting equipment.

• Attach 3/4" garden-hose threads to your city water inlet or spigot.
• Use the 1/4" NPT air quick plug for secure compressed-air connection.
• Open and close the brass shut-off valve to blow out selected lines.
• Schrader plug fits into standard service ports for efficient blowout.

What materials and ratings should I expect from the EVOULTES kit?

All primary fittings are lead-free brass certified under 0.25% lead content for safer potable-water contact. The included hybrid rubber hose tolerates wide temperature ranges and high pressure so it won’t stiffen or fail during cold-weather service.

• Lead-free brass fittings for corrosion resistance and potable-water safety.
• 17" hybrid rubber blow hose rated to 300 PSI and -22°F to 250°F.
• Standard 3/4" male and female garden-hose threads for universal fit.
• 1/4" NPT air quick plug for common compressor couplers.

How do I prevent leaks and ensure a reliable winterization process?

The kit includes Teflon tape to seal threaded connections and reduce air leaks during blowout. The machined brass threads and the shut-off valve create precise, durable seals so you can work quickly without repeated tightening.

• Wrap Teflon tape around male threads before connecting to prevent leaks.
• Use the shut-off valve to isolate sections and verify seals fixture-by-fixture.
• Inspect hose and fittings for wear; replace any damaged parts before use.
• Tighten connections with hand tools; avoid over-torquing brass fittings.

Can I use this kit beyond RV winterizing?

Yes—the male-threaded plug and versatile adapter layout let you apply compressed air to other outdoor systems like sprinklers and small boat plumbing. Adding a female-to-female converter extends compatibility to many irrigation and gardening setups.

• Winterize travel trailers, motorhomes, campers and personal watercraft.
• Use with sprinkler systems and outdoor plumbing via a female-to-female converter.
• Portable 17" hose reaches tight inlet locations without strain.
• Compact brass components pack easily for seasonal storage.

Who this is for: This kit is aimed at RV owners, campgrounds and maintenance pros who want a compact, durable solution to remove water from plumbing before freezing temperatures. It’s also useful for homeowners and landscapers who need a small, reliable adapter to blow out garden hoses, sprinkler lines and other outdoor plumbing. If you need lead-free brass fittings, a built-in shut-off and a short, resilient hose that handles high pressure and wide temperatures, this EVOULTES winterizing kit is built for that job.
