We also see customers replace just the leaking hose without inspecting the trim cylinder seals — if the hose has deteriorated from age or heat, it’s worth checking the o-rings and seals in the trim cylinders during the same service to avoid revisiting the job.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563897716772,"sku":"864960","price":107.4,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/48f03a4d-c727-4773-a5fe-9dbe6d9c3855.png?v=1789417110","url":"https:\/\/marisolmarine.com\/products\/merc-877","provider":"Marisol Marine Company","version":"1.0","type":"link"}
