Special accessories

Phtalate-free 3/4" garden hose for connecting the submersible pres-
sure pump with the application equipment.
Also available in other lengths and qualities.

with G1 (33.3 mm) connection thread and 3/4" and 1" hoses, includ-
ing union nut, hose clamp, flat packing and check valve.
To connect pumps to the interior thread of water connections.
