Boltigen RV Winterizing Kit with Pressure Gauge & Control Valve — Upgraded 0–80 psi, 60" Reinforced Hose

Boltigen Upgraded RV Winterizing Kit with Pressure Gauge & Control Valve is a complete blowout set that lets you purge and protect RV, boat, and outdoor plumbing lines from freezing using measured air pressure.

When temperatures drop, trapped water in hoses and onboard plumbing can freeze, expand and cause costly damage. This Boltigen kit pairs a clear 0–80 psi analog pressure gauge with a shut-off control valve, brass adapters, washers and a 60-inch reinforced hose so you can safely and precisely blow out water lines with an air compressor instead of relying on toxic antifreeze.

How does the pressure gauge and shut-off valve help during winterizing?

The integrated pressure gauge lets you monitor air pressure in real time so you don’t over-pressurize fittings while clearing water. The shut-off valve provides a quick way to start and stop airflow without disconnecting tools or losing pressure readings.

• 0–80 psi brass-cased gauge for readable, reliable pressure checks
• Inline shut-off valve for controlled bursts and safe stops
• Prevents over-pressurizing sensitive RV plumbing components
• Clear visual feedback reduces guesswork versus manual blowout

What connectors and hose fittings are included, and what do they fit?

The kit includes a 3/4" GHT-compatible connector set that fits standard garden hose and many RV water inlets. Two seal washers and a female-to-female adapter expand compatibility so you can link to most campground spigots, hose threads and onboard fittings.

• 3/4" GHT male/female compatibility for common RV and garden hose connections
• Female-to-female adapter to bridge different thread orientations
• Two replacement seal washers to ensure leak-free seals
• Thread sealing tape included for tight, pressure-safe joints

How durable and safe is the Boltigen winterizing kit for repeated seasonal use?

All wet-contact metal components are brass or zinc-alloy to resist corrosion and maintain thread integrity over many seasons. The hose is reinforced synthetic rubber designed to flex in cold conditions without cracking or kinking, and the gauge uses a metal case to protect its internals.

• High-quality brass adapters with frosted finish resist corrosion
• Zinc-alloy shut-off valve built for frequent operation
• Reinforced synthetic rubber 60" hose for cold-weather flexibility
• Metal-cased gauge offers impact protection and clear readings

What can I winterize with this kit besides an RV?

Beyond travel trailers, the kit works for boats, garden sprinkler lines, outdoor faucets and many campground or marine plumbing systems. Its thread standards and included adapters make it a practical tool for most outdoor water systems you want cleared before freezing weather.

• Boat on-board plumbing and bilge systems
• In-ground or above-ground sprinkler zones and valves
• Outdoor faucets, garden hoses and washdown lines
• Seasonal maintenance for cabins, sheds and portable toilets

Who is this for: Boltigen's upgraded RV winterizing kit is designed for RV owners, boaters, campground operators and homeowners who prefer a mechanical, antifreeze-free winterization method. It's well suited to DIYers who want measurable control during blowouts, maintenance pros who need durable hardware for repeated seasonal use, and anyone aiming to protect plumbing without chemicals.
