The collars create the watertight yet removable joint between the union body and the check valve, allowing the valve to be removed for service without cutting the pipe.\u003c\/p\u003e\n\u003ch3\u003eKeep Your Dual Union Connections Leak-Free and Serviceable\u003c\/h3\u003e\n\u003cp\u003eDual union collar threads are subject to cyclic loading each time the check valve is removed for inspection and reinstalled, which gradually reduces the thread engagement over time. When a collar no longer seals reliably or develops visible thread wear, replacing it with a new collar from this set restores the watertight connection without replacing the entire check valve assembly. The set of two provides both collars needed for a complete single check valve installation.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePipe Size\u003c\/td\u003e\n\u003ctd\u003e5 cm (2 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eSet of 2 collars\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible With\u003c\/td\u003e\n\u003ctd\u003eAquascape Dual Union Check Valve 2.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeal Type\u003c\/td\u003e\n\u003ctd\u003eRubber gasket (no thread sealant required)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePVC thermoplastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cp\u003eThread each collar onto the corresponding union body of the Dual Union Check Valve 2.0 by hand until the gasket contacts the seating face. Tighten each collar one half-turn further to compress the gasket and create a watertight seal. Do not use thread sealant tape on union collars as the gasket provides the seal. To service the check valve, unscrew both collars by hand and remove the valve body. Inspect the gaskets each time the valve is removed and replace if they show flattening or cracking.\u003c\/p\u003e\n\u003cp\u003eIdeal for maintaining Aquascape Dual Union Check Valve 2.0 installations in pond and waterfall systems where the locking collars have worn, cracked, or lost their sealing function after multiple service cycles.\u003c\/p\u003e","brand":"Aquascape","offers":[{"title":"Default Title","offer_id":52698424181055,"sku":"AQ-48021","price":11.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/8260\/9215\/files\/aquascape-replacement-parts-default-title-aquascape-dual-union-check-valve-2-0-threaded-collar-set-of-2-43287372005695.webp?v=1776379652","url":"https:\/\/pondsonline.ca\/products\/aquascape-dual-union-check-valve-20-threaded-collar-set-of-2","provider":"Ponds Online","version":"1.0","type":"link"}
