Rigid PVC cuts cleanly with a PVC pipe cutter, hacksaw, or miter saw. Deburr the cut end with sandpaper or a deburring tool before joining to fittings to ensure a leak-free solvent-weld or push-fit connection. The smooth-bore interior makes it easy to achieve a clean, square cut.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-cta\"\u003e\n    🛒 Select your \u003cstrong\u003esize (OD × wall thickness) and pack quantity\u003c\/strong\u003e above, then add to cart — ships from our US warehouse.\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"20mm x 2mm \/ 500mm \/ 1 Pcs","offer_id":52332916900114,"sku":"GLFBNHHMESSIGUAN0693x1","price":66.76,"currency_code":"USD","in_stock":true},{"title":"25mm x 2mm \/ 500mm \/ 1 Pcs","offer_id":52332916932882,"sku":"GLFBNHHMESSIGUAN0694x1","price":67.12,"currency_code":"USD","in_stock":true},{"title":"32mm x 2mm \/ 500mm \/ 1 Pcs","offer_id":52332916965650,"sku":"GLFBNHHMESSIGUAN0695x1","price":67.85,"currency_code":"USD","in_stock":true},{"title":"40mm x 2mm \/ 500mm \/ 1 Pcs","offer_id":52332916998418,"sku":"GLFBNHHMESSIGUAN0696x1","price":69.21,"currency_code":"USD","in_stock":true},{"title":"50mm x 2.4mm \/ 500mm \/ 1 Pcs","offer_id":52332917031186,"sku":"GLFBNHHMESSIGUAN0697x1","price":71.06,"currency_code":"USD","in_stock":true},{"title":"20mm x 2mm \/ 500mm \/ 2 Pcs","offer_id":52332917063954,"sku":"GLFBNHHMESSIGUAN0693x2","price":131.23,"currency_code":"USD","in_stock":true},{"title":"25mm x 2mm \/ 500mm \/ 2 Pcs","offer_id":52332917096722,"sku":"GLFBNHHMESSIGUAN0694x2","price":131.99,"currency_code":"USD","in_stock":true},{"title":"32mm x 2mm \/ 500mm \/ 2 Pcs","offer_id":52332917129490,"sku":"GLFBNHHMESSIGUAN0695x2","price":133.4,"currency_code":"USD","in_stock":true},{"title":"40mm x 2mm \/ 500mm \/ 2 Pcs","offer_id":52332917162258,"sku":"GLFBNHHMESSIGUAN0696x2","price":136.26,"currency_code":"USD","in_stock":true},{"title":"50mm x 2.4mm \/ 500mm \/ 2 Pcs","offer_id":52332917195026,"sku":"GLFBNHHMESSIGUAN0697x2","price":139.79,"currency_code":"USD","in_stock":true},{"title":"20mm x 2mm \/ 500mm \/ 3 Pcs","offer_id":52332917227794,"sku":"GLFBNHHMESSIGUAN0693x3","price":195.77,"currency_code":"USD","in_stock":true},{"title":"25mm x 2mm \/ 500mm \/ 3 Pcs","offer_id":52332917260562,"sku":"GLFBNHHMESSIGUAN0694x3","price":196.86,"currency_code":"USD","in_stock":true},{"title":"32mm x 2mm \/ 500mm \/ 3 Pcs","offer_id":52332917293330,"sku":"GLFBNHHMESSIGUAN0695x3","price":198.95,"currency_code":"USD","in_stock":true},{"title":"40mm x 2mm \/ 500mm \/ 3 Pcs","offer_id":52332917326098,"sku":"GLFBNHHMESSIGUAN0696x3","price":203.25,"currency_code":"USD","in_stock":true},{"title":"50mm x 2.4mm \/ 500mm \/ 3 Pcs","offer_id":52332917358866,"sku":"GLFBNHHMESSIGUAN0697x3","price":208.61,"currency_code":"USD","in_stock":true},{"title":"20mm x 2mm \/ 500mm \/ 4 Pcs","offer_id":52332917391634,"sku":"GLFBNHHMESSIGUAN0693x4","price":260.24,"currency_code":"USD","in_stock":true},{"title":"25mm x 2mm \/ 500mm \/ 4 Pcs","offer_id":52332917424402,"sku":"GLFBNHHMESSIGUAN0694x4","price":261.65,"currency_code":"USD","in_stock":true},{"title":"32mm x 2mm \/ 500mm \/ 4 Pcs","offer_id":52332917457170,"sku":"GLFBNHHMESSIGUAN0695x4","price":264.51,"currency_code":"USD","in_stock":true},{"title":"40mm x 2mm \/ 500mm \/ 4 Pcs","offer_id":52332917489938,"sku":"GLFBNHHMESSIGUAN0696x4","price":270.22,"currency_code":"USD","in_stock":true},{"title":"50mm x 2.4mm \/ 500mm \/ 4 Pcs","offer_id":52332917522706,"sku":"GLFBNHHMESSIGUAN0697x4","price":277.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Main-03_72354a7b-a75e-4778-bd1e-dcbd01fbb9c7.jpg?v=1780989071","url":"https:\/\/homediyer.com\/de\/products\/green-pvc-round-tube-20-50mm-rigid-pipe-500mm-aquarium-pond","provider":"HomeDIYer","version":"1.0","type":"link"}
