Our standard thread mouthpieces are compatible with Giardinelli, Moosewood, Stork, Warburton, Atkinson, and other screw rim mouthpieces. They are available in standard (.650") and wide (.675") sizes. Listed from in families from shallowest to deepest.

Our standard thread rims fit any of our standard and wide mouthpieces. Choose an Standard or Plus diameter for standard cups and a wide for wide cups. As long as you stay in the correct size range any design rim will fit any of our cups.

Our metric cup series offers wider inside diameters and compatibility with PHC and Paxman mouthpieces. (Even though they're called "Metric", the thread size is .800"x36.) All our metric cups share a 17.5mm inner diameter and fit our metric series rims.

Metric rims are designed to fit our metric cups and have different threads from our standard thread line. They are available in 17.5, 18, and 18.5mm inside diameter, as measured 1.25mm from the crown of the rim.

Our Replica mouthpieces are copies of significant mouthpieces from the past. Both inside and outside shapes are faithfully reproduced. Replica mouthpieces are sold as a cup/rim set. The cup contours and rims are also available in our regular lines.
