This accessory fits directly onto the NTW1 drive and delivers controlled, ratcheting torque output for HVAC refrigerant line fitting connections. The round ratchet head format is standard in HVAC service for tightening flare and service valve fittings without over-torquing. Licensed HVAC technicians and refrigeration service pros use this type of head when working on split systems, mini-splits, and refrigerant circuits where proper torque is required.\u003c\/p\u003e\n\u003cp\u003eThe ntwr38 is intended for use with the NAVAC NTW1 electronic torque wrench in residential and light commercial HVAC service applications. It is suited for installations and service calls where 3\/8-inch refrigerant fittings are involved, including flare nut connections on copper tubing at outdoor condenser units and indoor air handlers. This head allows the technician to maintain accurate torque without needing a separate wrench or adapter for this fitting size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch round ratchet head for precise fitting engagement\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for the NAVAC NTW1 torque wrench\u003c\/li\u003e\n  \u003cli\u003eRatcheting mechanism allows work in tight spaces with limited swing arc\u003c\/li\u003e\n  \u003cli\u003eReplacement or spare head for field service kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the NAVAC NTW1 torque wrench.
