Replace washers as a complete set at each fastener location rather than individually — consistent clamping force across all connection points helps maintain proper pump assembly integrity. Match the 1\/2\" size designation to the fastener specification in your EQ-Series installation manual before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960103395603,"sku":"350063Z","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-stainless-steel-split-lock-washer-1-2-eq-series-commercial-pump-350063z.webp?v=1780435462","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_350063z","provider":"Poolaroo","version":"1.0","type":"link"}
