Block Tester Powder & Bottle Refill for Combustion Gas Test

A block tester powder and bottle refill used to keep compatible combustion gas test kits ready for use. It is intended as a replacement or top-up for an existing tester when checking for combustion gases in a vehicle cooling system during head gasket fault diagnosis.

Used in garage work, workshop servicing and home vehicle maintenance, this refill suits anyone already carrying out cooling system diagnostic checks with the matching tester kits. It is useful when the original contents have been used up and a job still needs finishing, whether you are investigating suspected head gasket trouble, confirming combustion gas contamination, or keeping a regular test kit prepared for repeat use.

Supplied as powder with bottle, this refill is for use with block tester kit CT1133 and also fits block tester kit CT3923. Keeping the correct refill with the tester helps avoid using the wrong contents and makes it easier to keep the kit complete between jobs. For mechanics, garages and home users who already rely on this type of tester, it is a practical spare to keep close to hand for regular maintenance and fault-finding work.
