It is listed with the S7M120, S7M400, S8M150 and S8M500 models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bulkhead is the port through the filter tank wall, and the elbow turns the flow at that point. It is a joint that has to seal under pressure for years. When the assembly cracks, distorts or the sealing face is chewed up, the symptom is a weep or a drip at the tank that no amount of tightening cures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the model, not the media\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOur source describes this part both as a Modular Media SM series D.E. filter part and as a System:3 SM cartridge filter part, for the same four model numbers. Rather than choosing between those readings, match your filter to the model numbers listed above. The bulkhead o-ring is a separate part, so inspect it while the assembly is out.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48625749131476,"sku":"STA-051-2951","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1847f5a5-2b22-40ef-a2f9-597793d65282.gif?v=1788691661","url":"https:\/\/www.activepoolsupply.com\/products\/elbow-and-bulkhead-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
