100% Satisfaction: The freely rotating connection nut ensures a secure fit with your faucet. Using sealing tape will make connecting your garden hose even faster and easier.

For better seal testing and effective compression force, the screws on the product you receive are pre-tightened upon first use—this is normal. Compatible with garden hoses, this lateral swivel connector swiftly attaches to standard spouts or hose connections. Long-term use without leaks or corrosion - The connector withstands up to 8 kg water pressure without leakage and remains rust-free year-round. You can even connect additional hoses to backyard sinks or drip irrigation systems. Ideal for home, garden, and backyard use.
