White-Rodgers thermocouple, 48 inch stainless probe, threaded fitting

Emerson Climate Technologies

Emerson Climate Technologies White-Rodgers H06E048S1 Thermocouple 48 in 18 to 30 mV

SKU CH-04WF-PQ5TT

A 48-inch standard coaxial thermocouple producing 18 to 30 mV for standing-pilot systems, with a 3/16-inch stainless-steel probe and universal adapter fitting

  • Product typeStandard Coaxial
  • Universal fit for Honeywell, Johnson Controls, Robertshaw and White-Rodgers pilots
  • 48 in probe reaches deep burner chambers without extra tubing
  • 18 to 30 mV output keeps standing-pilot gas valves energised reliably
  • Stainless-steel element resists corrosion in LP and natural-gas service
  • Threaded 11/32 in connection with included adapter simplifies replacement

Direct Replacement Thermocouple

This White-Rodgers thermocouple serves as a direct replacement for standing pilot systems in heating equipment. It fits Honeywell, Johnson Controls, Robertshaw and White-Rodgers valves, and the universal adapter fitting simplifies installation across multiple brands.

Stainless-Steel Element Output

The stainless-steel probe produces an output of 18 to 30 mV, delivering reliable millivolt signal strength for consistent gas-valve operation. Threaded process connection of 11/32 in ensures a secure, gas-tight seal during normal service.

Sustained Pilot Performance

A 48 in probe length positions the sensing element securely in the pilot flame for continuous operation. The standard coaxial construction maintains stable output over extended heating cycles without signal decay.

Questions about this item

How do I install the 48 in thermocouple and which step is often missed?

Thread the 11/32 in process connection into the gas valve, secure the probe in the pilot bracket, then attach the universal adapter fitting — the step most often missed is tightening the adapter before lighting the pilot.

What maintenance or replacement will the stainless steel element need later?

The stainless steel probe should be inspected each heating season for soot or corrosion; if output drops below 18 mV the thermocouple must be replaced.

What limit appears first during sustained pilot operation?

Continuous exposure to the standing pilot flame can cause the 3/16 in diameter probe to degrade, reducing millivolt output toward the lower end of the 18 to 30 mV range.
