Silicone Coolant/Heater Hose
Series 6623 is a hardwall silicone coolant/heater hose designed to transfer high temperature solutions between the radiator and engine on automobiles, buses, mobile/off-road equipment, trucks and any engine incorporating a radiator application. The hose meets or exceeds SAE J20R2 Class A, ISO 1307-1997 and TMC RP303B requirements, with a temperature range of -76° to + 392°F (-60°C to +200°C). The hose construction incorporates multiple plies of textile reinforcement for durability, a helical wire for limited suction capability and collapse/kink resistance, and resists collant suctions, aging, cold leaks, cracking, delamination, ozone and peeling. Series 6620 is manufactured on 130-foot mandrels- providing the longest and most flexible continuous hose lengths in the industry- for tight dimensional tolerances and maximum inventory utilization.
