Thermostat Options

Stuffing Box Assembly

The Stuffing Box Assembly is used to seal the thermostat capillary when the sensing bulb (3/8″ max. OD) is immersed directly in a liquid rather than in a thermowell. The Stuffing Box consists of six slotted washers used to compress a graphite packing into a 3/8″ NPT male pipe thread fitting. Assembly Instructions Feed sensing bulb through hole in upper and lower fitting. Insert washers and packing into top cavity of lower fitting. Upper fitting then screws into lower fitting, creating the seal. Part Number: TST-109-101

Thermowells

Stainless Steel or Plain Steel: Thermowells provide protection for bulb and capillary sensors. They are supplied with a 1/2″ NPT male thread for mounting and a 3/8″ NPT internal thread that can be used with the stuffing box assembly to secure the capillary to the well. ID: 0.50″, OD: 0.56
