Recommended to lubricate the piston rod yearly, this will help extend the lifetime of the hydraulic cylinder. Don't use solid grease, as dust particles \"glues\" easily onto the piston rod and can damage the rubber. Also do not forget to unlock the vent in the winter if leaving the vent openers installed. Even a even a weak winter sun can heat the hydraulic cylinder sufficiently to make it start pushing the piston rod outwards.\u003c\/p\u003e","brand":"Grow Organic","offers":[{"title":"Default Title","offer_id":49535733694692,"sku":"SEF115","price":25.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/0290\/0196\/files\/automatic-vent-opener-gigavent.jpg?v=1785402021","url":"https:\/\/groworganics.shop\/products\/automatic-vent-opener-gigavent-0x3btf","provider":"Westbridge","version":"1.0","type":"link"}
