This simple, economical 35mm adapter kit allows easy fitting directly into the top radiator hose. It is intended as an accessory for Davies Craig Thermatic switches with part numbers #0400, #0401, #0404, #0444 and #0445.

Just fit the probe into the compression fitting, remove about 17mm (2/3”) of radiator hose, fit the adaptor between each hose and secure the hose clamps. The kit comes complete, as shown, for a watertight and effective probe installation. Extra rubber sleeves are supplied to enable fitment to radiator hose sizes from 32mm to 40mm (1.25"-1.50") diameter. Suits all temperature sensors with either a 5mm (3/16") or a 6mm (1/4" outside diameter and temperature gauge senders with 6mm (1/4") NPT thread.

Two 1/4" NPT holes allow the fitment of a sensor and or air bleed. Should you only need one hole, a bung is included.
