VEVOR 75ft Heated Water Hose for RV, Heated Drinking Water Hose Antifreeze to -45°F, Automatic Self-regulating, 5/8" I.D. with 3/4" GHT Adapter, Lead and BPA Free

Can I insulate this as well without knowing where the sensors are? I need to insulate the end fittings so they don't freeze but worried about covering the blue hose itself.Thanks so much in advance for your reply. Have a wonderful productive day. Sam
