One end of the adapter has a quick-connect plug, commonly known as 1/4" Industrial Interchange plug, designed to connect to most air compressors. The other end of the adapter has a female garden hose faucet/spigot/spout connection. If your sprinkler system does not currently have a garden faucet, the winterization instructions which are included show the proper location to install a garden faucet.
Winterizing your sprinkler system is easy with this adapter. We use only the finest quality and most durable parts to fabricate this industrial quality, outdoor rated winterizer. The water and oil resistant Insta-grip hose is made in the USA. We use food-grade vegetable oil and non-toxic plumber's pipe dope only in the installation process.
