• Material: PVC-C, heat resistant
• Dimension: acc. to DIN 8079/80
• Colour: agate grey RAL 7038
• Pipe length: 5000mm, with plain ends
• Note 1: DVGW certification
• Attention: Pressure rates refer to operating temperatures at 20°C. Higher temperatures and aggressive flow media reduce pressure load (see above DIN and our technical documentation). Pressure load capacity has to be determined in consideration with safety demands of the respective applications and calculated in accordance.
