Standard Universal Thermocouple 900mm is rated 4.5 out of 5 by 32.
Rated 2 out of 5 by from OK, just As someone else noted, they burn out fairly quickly, I've also tried the more expensive Super model, also burnt through in less than 12 months, prob not worth the extra. On the plus side the're available and easy to change, just keep a spare to hand.

Rated 4 out of 5 by from Good piece of kit Needed a new Thermocouple and as usual Screwfix had one. Came with an assortment of unions but I use the old ones as I know they screw in OK. The coil seemed well wound but it un-coiled OK and shaped easily to fit to the boiler. Heating up and running again in no time.

Rated 4 out of 5 by from Perfect for an old boiler! Fitted to my 30 year old Baxi back boiler in just a few minutes. Works perfectly and had all the bits needed. I don't know if it will last as long as the old one but it was so inexpensive who cares?
