{"product_id":"clamp-ram-cam-optiflo","title":"Pentair Clamp Ram and Cam, Optiflo","description":"\u003cp\u003eThe Pentair 357239 is the clamp ram and cam for Optiflo pumps, also listed for the Jacuzzi JPA Pro Grade above ground pump. The source data also refers to it as the clamping ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe two halves of the pump housing are held together by a clamp band, and the ram and cam are the hardware that closes it. The cam levers over center, the ram carries the load, and the joint pulls up tight against its seal. It is a piece that takes real force every time the pump is opened and closed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptom\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA pump that seeps at the housing joint is either a seal problem or a clamp problem. If the seal is in good shape and the clamp still cannot draw the joint closed, the ram and cam have worn and there is nothing to be gained from leaning on the lever harder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOn the dimensions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe inner diameter is given as 5-1\/8\". The outer diameter is quoted two ways in the source data, once as 10-1\/8\" ear to ear and once as 6-1\/2\", so both are listed here rather than guessing at which is meant. If the fit is at all in doubt, measure the clamp you are replacing.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627972374740,"sku":"PAC-101-7239","price":26.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ef849944-4396-47ef-929f-55938a26baa3.jpg?v=1788732022","url":"https:\/\/www.activepoolsupply.com\/products\/clamp-ram-cam-optiflo","provider":"Active Pool Supply","version":"1.0","type":"link"}
