Some snorkel heads have a pipe diameter of 77mm (3 inch) and others 88mm (3.5 inch)
With this adapter you can fit a 88mm head on a 77mm snorkel and vica versa
The adapter does NOT include the clamps
A good example is the round snorkel head. It has a pipe diameter of 88mm but some of the snorkels which fit the older vehicles like the KZ-TE Prado 90 has a 77mm pipe. By using this adapter you can now fit the round head on those snorkels.
