AMI
AMI offers a low cost option for these widely used quick-connect fittings. Designed with speed and ease in mind, the push-in QC style quickly forms a tight seal to the tubing used in home RO Systems without any tools or threaded nuts. This is particularly desirable for connection to system components that need to be removed for regular service such as membrane housings and in-line filters. These sturdy, high quality polyethylene fittings are intended for use in residential RO applications with pressures up to 150 psi.
