With a full 500-foot spool on hand, installers and service techs are ready for back-to-back jobs without running short. Whether building a new higher-capacity installation, upgrading existing lines, or restocking inventory, this 3\/8 inch John Guest polyethylene tubing in black is a professional-grade choice for dependable, higher-flow water treatment plumbing.\u003c\/p\u003e","brand":"Nelsen Corporation","offers":[{"title":"Default Title","offer_id":45668837785653,"sku":"PT03-S-BLACK","price":289.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/pt03-s-black.jpg?v=1782535221","url":"https:\/\/watersoftenerplus.com\/nl-eu\/products\/3-8-poly-tubing-500ft-spool-blk","provider":"Water Softener Plus","version":"1.0","type":"link"}
