Heat Conduction Tube Systems  Manufacturers, Traders, Suppliers

Roswel is an international company and has been in existence since 2009 and has since developed into a specialist with a wide range of connectors and piping systems, many of which (connectors; threaded connectors; compression connectors and compression fittings) and hoses (PE polyethylene, PA polyamide, PU polyurethane, PB polybutylene, PTFE, PE-RT underfloor heating hose, multilayer) are available directly from stock.
