ABSTRACT:
A conduit has a first end and interior and exterior surfaces extending downstream from the first end. A strainer has a first end and a second end. An upstream portion of the strainer is positioned engaging a projection on the interior surface of the conduit to resist downstream shifting of the strainer. A strainer body extends at least partially downstream of the upstream portion. The apparatus may be used as a strainer/coupler and may be used to filter water in a chiller apparatus.
