SYS3 ORING 6.9 OD 6.35 ID

The O-Ring for Pentair WhisperFlo XF / IntelliFlo XF Strainer Lid -- 6.9 OD x 6.35 ID (35505-1440) is a replacement trap/strainer cover o-ring for Pentair WhisperFlo XF and IntelliFlo XF series pump strainer lids. Measuring 6.9-inch outside diameter by 6.35-inch inside diameter, this large-format lid o-ring seals the XF strainer lid to the XF strainer body, preventing air infiltration into the suction side of the pump. A deteriorated lid o-ring causes air bubbles in the return lines and loss of prime. Replace whenever the strainer lid is removed for basket cleaning. Compatible with Pentair WhisperFlo XF and IntelliFlo XF pump series.
