NO LONGER AVAILABLE but we do have a substitute.
SUBSTITUTE
Working with Liss we have developed the following substitute for the pierce pin (9104) and pierce pin seal (9103) for the glass siphon. You can substitute the pierce pin (9003) and pierce pin seal (9004) from the Liss Stainless Siphon. CAUTION: you must replace both pieces. The pierce pin and pierce pin seal are designed to work together. We have tested the combination pierce pin (9003) and pierce pin seal (9004) from the stainless siphon and they work fine in the glass siphon.
