TO 43mm Twist Lid black - Pack of 40 units

01 · COMPATIBILITY

TO43 GPI 2010: the jar finish determines the fit

These four-lug lids work with a TO43 Twist-Off finish following the GPI 2010 profile. Do not choose them from the outside diameter alone: similar jars may use different heights, lugs and thread profiles. Confirm the finish code or test lid and jar before packing the whole batch.

02 · A SOUND CLOSURE

A new lid still needs a compatible jar and process

Check the glass rim for chips, product residue and moisture around the sealing area. Set the lid straight and apply the torque specified for the jar and capping line. The final closure depends on the lid–jar combination, filling conditions, temperature and process; the lid alone cannot guarantee a hermetic seal or vacuum.

03 · PASTEURISATION

Up to 100 °C for 60 minutes according to the data sheet

The specification covers pasteurisation at up to 100 °C for 60 minutes. This is not a general authorisation for higher-temperature sterilisation: a more demanding process must be validated for the exact lid, sealing compound, jar and working pressure.

04 · DESIGN AND CHOICE

A small lid for small-format jars

The TO43 size suits small-jar lines where the black finish adds contrast without introducing a printed motif. Confirm the GPI 2010 finish: “43 mm” does not mean it will close any jar opening that appears to measure 43 mm.

FROM THE APIARY

A Twist-Off does not screw on like a bottle cap: the four lugs ride up a short ramp and the whole closure is a quarter turn. Sit it flat until you feel it settle, turn to the stop and leave it there: carrying on does not seal better, it bends the lug and leaves the jar impossible to open. If it grates or feels like the thread has stripped, lift it off and set it down again — there is no thread to strip, a lug has ridden over its ramp.

05 · BEFORE YOU BUY

A small dent can become a failed closure

Keep the lids packaged, clean and dry between 5 and 35 °C and at no more than 70% relative humidity. The sheet states a storage life of up to two years. Do not place weight on them, and reject rusty, dented or distorted units before filling. The pack contains 40 lids; jars and capping equipment are not included.
