Pizzi code 0024 is a nozzle for grooves within the manufacturer's nozzle range for PVA glues. The exact official listing assigns this code to the published 4 × 30 mm configuration.

This nozzle is classified for panel and cabinet processing involving grooves, edges, dado joints, and biscuit-joint work. Its shaped contact format is intended for glue application in a prepared groove rather than for dowel-hole, surface-roller, or adjustable-edge applications.

Codes 0025, 0026, 0027, and 0028 are separate groove-nozzle variants published as 5 × 30 mm, 6 × 30 mm, 8 × 30 mm, and 10 × 30 mm. Code 0024 must be selected only where the required groove preparation matches the exact 4 × 30 mm configuration.
