This replacement set includes the flexible tube and plastic end cap for the R.G. Hardie & Co. Blowpipe Split Stock water trap. The flexible tube collects excess moisture inside the bagpipe, which can be easily emptied by removing the blowpipe from the bagpipes.
 
The split stock design allows the tube to be removed when seasoning a leather pipe bag. The replacement tube and end cap are suitable for use with split stocks fitted to any pipe bag, particularly leather bags and synthetic bags without a zip.
