Frequently Asked Questions

Q: Are these foam nozzles compatible with all polyurethane spray foam cans?

A: These replacement nozzles are designed to fit most standard polyurethane expanding foam cans and applicator guns. We recommend checking the nozzle connection diameter of your specific foam can before ordering to ensure compatibility.

A: Each nozzle measures 18 cm (approximately 7.09 inches) in length, providing excellent extended reach for filling deep cracks, gaps behind fixtures, and other hard-to-access areas.

Q: Can these nozzles be reused after the foam cures?
