Fit a tap to hose connector set properly and stop drips at the tap. Step-by-step for Hoselink 18mm fittings, plus washer checks and common mistakes.
Quick answer
To install a tap to hose connector set without leaks, match the connector to your hose diameter, hand-tighten the tap adapter, and push the hose connector until it clicks. If it drips, check the washer first. For 18mm hose, use the Hoselink 18mm Tap to Hose Connector Set and never force it onto standard 12mm fittings.
Check your hose diameter before you buy or fit anything
Hose connectors are sized to the hose, not the tap. A connector made for 12mm hose will not seal on 18mm hose, and an 18mm connector will not grip a 12mm hose properly. Measure the outside diameter of your hose or check the printing on the hose itself. If you are unsure, buy a connector set that matches the hose you already own rather than guessing at the tap end.
Prepare the tap and hose end
Clean the tap outlet with a cloth and check the thread for burrs or old sealant. Cut the hose end square if it is frayed or crushed, then push the hose onto the connector firmly. A clean, square cut lets the connector grip evenly and reduces the chance of a leak at the hose side.
Fit the tap adapter and hose connector
Screw the tap adapter onto the tap by hand until it is snug. Do not use pliers, because over-tightening can crush the washer or crack the plastic. Then push the hose connector onto the hose until it clicks or seats fully. Pull gently on the hose to confirm it is locked in place before turning the water on.
Test and fix drips at the tap
Turn the tap on slowly and watch the connection. A drip at the tap usually means the washer inside the tap connector is worn, missing, or seated crookedly. Unscrew the connector, remove the washer, and replace it with the correct size. The Hoselink 1" Washer for Universal Tap Connector is made specifically for Hoselink fittings and 1" tap connections, so it is the right spare if that is your setup.
Step-by-step: leak-free tap to hose connector installation
- Match connector to hose size: Measure your hose outside diameter or read the size printed on it. Use 18mm connectors only with 18mm hose, and 12mm connectors with 12mm hose. Checkpoint: if the connector slides on too easily or will not go on at all, it is the wrong size.
- Clean and inspect the tap: Wipe the tap outlet and thread. Look for rough edges that could cut the washer. If the tap has a removable aerator, take it off first. Common mistake: leaving old rubber or grit on the thread, which prevents a tight seal.
- Hand-tighten the tap adapter: Screw the adapter on until it feels snug. Do not force it or use tools. The washer needs to compress evenly, not be crushed. Checkpoint: a slight turn past snug is fine, but stop if you feel resistance.
- Push the hose connector onto the hose: Cut the hose end square if needed. Push the connector on until it clicks or bottoms out. Tug gently to confirm it is locked. Common mistake: not pushing far enough, which causes the hose to blow off under pressure.
- Turn water on slowly and check: Open the tap partway and watch both the tap end and hose end. A drip at the tap usually means the washer needs replacing. Next step: if it drips, replace the washer with the correct spare part for your tap size.
Product facts
- 18mm* Tap to Hose Connector Set: Specially designed for use with Hoselink’s 18mm hose fitting range; not compatible with standard 12mm fittings. 18mm diameter hoses are typically used in rural and commercial applications and provide a higher water flow rate than standard 12mm hoses and fittings. If you have 18mm hose, this set gives you the correct fit and flow. If you have 12mm hose, this set will not seal or grip, so choose a 12mm connector set instead.
- Hoselink Beginners Basic Pack: This bundle is ideal for anyone just starting out with Hoselink fittings. It contains a full set of Hoselink no-burst Connectors, a Spray Gun, and a Click-on Adapter Set you can use with your existing watering accessories. It converts one garden hose to the Hoselink ecosystem. If you are converting a single hose and want matching connectors, a spray gun, and adapters for your existing tools in one purchase, this pack covers the basics without buying each piece separately.
- 1" Washer for Universal Tap Connector: Leaking at the tap? This could be due to a damaged washer inside your Hoselink Tap Connector. Replacement washers are available. To replace, simply unscrew the connection from your tap, remove and replace the washer. Only suitable for 1” tap connections. These parts are made specifically for Hoselink fittings and are not suitable for other uses. A worn washer is the most common cause of a tap-end drip. Keeping a spare washer lets you fix the leak in minutes without replacing the whole connector.
