Dwyer Stainless Steel 304 ½" NPT Thermowell Length 4" TE-TNS-N043N-00

The Dwyer TE-TNS-N043N-00 is a high-quality, welded 304 stainless steel thermowell designed to safeguard immersion temperature sensors (such as Dwyer Series TE and TE-I) in water pipe applications. It isolates the sensor from direct contact with the process media while allowing accurate temperature measurement — perfect for HVAC chilled/hot water loops, boilers, chillers, and building automation systems.

Key Features

• Durable 304 Stainless Steel construction — excellent corrosion resistance for water and mild chemical environments
• Welded (fabricated) design — reliable and cost-effective for most HVAC and process applications
• 4 inch (100 mm) insertion length — ideal for standard pipe installations
• 1/2" NPT external process connection — easy threaded installation into pipes and fittings
• 1/2" NPSM internal thread — compatible with most immersion temperature probes/sensors
• Straight shank design for simple, straightforward mounting

The well is an accessory of Dwyer Water Pipe Temperature Sensor 4" PT1000 NEMA 4X TE-ITW-E0444-00
