The Jerry Max Screw Cap the EASY way to add a manual pump to a water jerry can for the ultimate campsite water system.

The Jerry Max Screw Cap is the core of the Jerry Max™ jerry can adapter system and is designed to fit popular water jerry cans with a 58mm screw thread. 

The Jerry Max Screw Cap will allow fitment of a variety of hand operated water pumps that are designed to fit into a 32mm mounting hole. We recommend the Companion hand pump but we have also seen it used with 32mm pumps from Trojan, Wanderer, Explore, Supex, and more. Click here for FAQ's on pump and jerry can compatibility.

It can also be used in conjunction with the Jerry Max Flexible Upper Cap to easily fit electric water dispenser pumps to a jerry can.

*Pumps sold separately.

The screw cap is designed and manufactured in Australia from food grade, UV stabilized, High Density Poly Ethylene (HDPE) that is BPA free. 

Not intended for use with hot liquids. Use of the original jerry can manufacturer's cap is recommended for storage and transport.
