This 4 mm plastic hole punch prepares an opening for a compatible drip irrigation fitting. Its broad hand grip helps you position the pointed tool against the tube while keeping the work controlled.

Confirm the fitting stem requires a 4 mm opening and that the tubing is suitable for punching. A connector described as 4 mm does not always specify its installation hole size. This illustrative tool view shows the grip and pointed working ends.
Turn the water supply off and drain the section. Choose a sound area away from damaged edges or existing holes. Support the tubing firmly so it cannot roll or collapse as you press the punch. Keep fingers clear of the tip and direct the tool away from your other hand.

Position the tool squarely and make the opening without enlarging it by sideways movement. Clear loose cuttings before inserting the compatible fitting. Check a completed connection before repeating the process along a new line.
Seat the fitting fully, then restore water gradually and inspect the opening for seepage. A loose fitting may indicate a damaged hole or an incompatible stem; forcing it deeper does not establish a seal. Select the required tool quantity separately from the 4 mm tool size. Browse drip fittings for the connections needed in your layout.
