The Altecnic 128-360 hoses are specifically designed for use with heat pumps. The flexible hoses allow for easy connection between the heat pump and associated equipment whilst reducing vibration to the pipework. The hoses are supplied with thick weatherproof insulation to reduce heat losses. The hoses are supplied in pairs.
Construction Details
The hoses have a swivel connection on the heat pump end and a compression joint to connect to the pipework inside or outside of the building. Threaded connections to BS EN ISO 228-1 Compression ends complying with BS EN 1252-2 for use with R250 (half hard) copper tube.
