Protect Your RV Plumbing This Winter

Simplify your seasonal maintenance with this heavy-duty brass blowout plug. Designed to connect directly to your air compressor, it flushes residual water from your lines to prevent freezing and bursting.

Solid Brass Universal Fit Easy Install

Versatile Applications for Every Water System

While essential for RV winterizing, this adapter is built for versatility. It serves as a reliable solution for protecting various plumbing systems against cold weather damage.

  • Recreational Vehicles: Ideal for motorhomes, travel trailers, and camper vans.
  • Marine Use: Effective for clearing water lines in boats during storage.
  • Home & Garden: Perfect for draining sprinkler systems, hoses, and outdoor faucets before the first freeze.

Fast, Tool-Free Installation

No need for wrenches or complicated setups. The large hexagonal base allows you to tighten the plug securely into your city water inlet by hand in seconds.

  1. Thread: Screw the brass plug into your RV’s city water inlet until snug.
  2. Connect: Attach your air compressor hose to the Schrader valve tip.
  3. Flush: Run the compressor to clear the lines, then remove the plug when finished.

Prevent Costly Freeze Damage

Water expands when it freezes, which can crack pipes, burst tanks, and ruin fixtures. By ensuring thorough drainage of your water system, this plug helps eliminate safety hazards and protects your investment during harsh winters.

Precision Dimensions & Design

Crafted with specific measurements to ensure a perfect fit on standard RV fittings. The design includes a protective cap to keep the valve core clean when not in use.

  • Total Height: Approx. 1.65 inches
  • Inlet Thread Diameter: 1.1 inches
  • Compressor Tip: 0.25 inches (Standard Schrader compatible)
  • Material: Solid Brass with Rubber Seal

Built to Last Season After Season

Unlike plastic adapters that become brittle in the cold, our blowout plug is machined from high-quality solid brass. It is resistant to corrosion and oxidation, ensuring smooth threads and a tight seal every time you use it.

Frequently Asked Questions

What comes in the package?
You will receive the brass blowout plug unit shown in the images. Depending on the option selected at checkout, this may include multiple units.
Does this work with all air compressors?
Yes, the top tip features a standard Schrader valve connection, making it compatible with most common air compressors and tire inflator chucks.
Is this suitable for freshwater tanks?
This plug is designed specifically for the City Water Inlet port to push air through the plumbing lines. It does not drain the fresh water tank itself.
How much air pressure should I use?
We recommend using low pressure (typically under 30-40 PSI) to safely flush out water without damaging your RV's internal plumbing components.
