For solvent-weld systems, apply solvent cement evenly to both the pipe and fitting before joining to create a permanent bond. For compatible push-fit systems, insert the pipe fully into the socket for a secure connection. Ensure all connections are aligned before final fixing.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e uPVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 21.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle:\u003c\/strong\u003e 90°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black, White, Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Overflow plumbing systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Solvent-weld or push-fit compatible\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Plastic Centre","offers":[{"title":"Black","offer_id":56831999148410,"sku":"OFKB90B","price":0.66,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":56831999181178,"sku":"OFKB90W","price":0.66,"currency_code":"GBP","in_stock":true},{"title":"Grey","offer_id":56831999213946,"sku":"OFKB90G","price":0.66,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/9377\/1130\/files\/OFKB90G.png?v=1776938033","url":"https:\/\/plasticcentre.co.uk\/products\/21-5mm-knuckle-bend-90-degree","provider":"Plastic Centre","version":"1.0","type":"link"}
