We supply spare corks discs to fit in the cap of hip flasks. There are many sizes of flask caps so we offer a variety of sizes.
The cork disc sits in the underside of the cap, to obtain the correct size please measure the inside diameter of the cap and choose from the sizes below
3/8″ | 1/2″ | 9/16″ | 5/8″ | 3/4″ | 1″ | 1,1/2″ | 13mm | 15mm | 16mm | 18mm | 20mm | 24mm | 29mm | 31mm
Our cork discs are 1mm thick which is usually the size of the original. Sometimes we are asked for much thicker corks which is usually an indication that the cap has lost its original filling/packing and this is now a void with nothing for a thin cork disc to fit against. If the flask is sent to us then we are happy to have our silversmith refill the top cap with his patent mixture and finally we fit a think cork disc.
The 2 pictures below show the before and after the cork has been reinserted.
