Replaces / Cross-Reference Part Numbers
This kit serves as a 3/4-inch GHT winterizing blow-out connection for clearing water lines with compressed air. No replacement part number is specified.
Compatibility & Fitment
Fits standard 3/4-inch GHT connections used on RVs, travel trailers, campers, motorhomes, boats, watercraft, cabins, outdoor faucets, spigots, sillcocks, garden hoses, soaker hoses, underground sprinkler irrigation systems, and underground drip irrigation systems. Verify that the connection uses standard 3/4-inch GHT threading before ordering.
The Schrader valve ends match standard car tire valves. The adapter can connect to a tire inflator, bicycle pump, or 1/4-inch quick-connect air compressor hose.
When to Replace
Replace the adapter if the brass body is cracked, the threads are damaged, the valve no longer holds or accepts air, or a sealing washer can no longer prevent leaks. Use it before freezing weather to remove residual water from RV and outdoor plumbing lines. Clearing the lines helps reduce the risk of freeze damage and cracked fittings without using liquid antifreeze.
Installation Tips
- Turn off the water supply and the RV water pump.
- Open the water heater pressure relief valve.
- Confirm the water inlet has standard 3/4-inch GHT threads, then install the appropriate male or female adapter with a rubber sealing washer. Apply the included PTFE thread seal tape where needed.
- Connect the air compressor or bicycle pump to the Schrader valve end.
- Open all faucets and drain valves so air can expel water from the lines.
- Remove the air source after the lines have been cleared and install the included valve-core dust caps.
- No special tools are required; the setup can be completed in minutes.
