    The one I previously owned had an air chamber that required air pressure. I could adjust it by adding air to the chamber. There is another company making a similar unit now that will replace the original Hydro-Coil unit. I think it is JS Air Cushion Stocks, 850 W Foothill Blvd # 21, Azusa, CA 91702, telephone (626) 334-2563.

    Jack Docwiller used to rebuild them or may have a new one. G-squared made replacement aluminum air filled and adustable for feel and lengthe of pull. I bought the last two they had years ago , but they may have made another run since then. Also Joe Shiozaki at J.S. air cushion may have some help. If your unit is not cracked it can be rebuilt if the end cap will come out. I have taken to placing a spring inside the inner chamber instead od replacing the O-ring and oil. They all eventually leak and make a mess. Let me know and I can talk you through it. Jeff

    I have what I think to be (from the descrition), the same devise. It has the ' valve core ' and the ability of adding air. Mine the comb moves forward with the pad. Keep in mind that when you add air to a certain point say 100#, then take the ' air source ' off, you lose may be 10#. As well as putting a pressure checker on it, you lose another 10#. Air Reservoir/tank very small! I wonder if any of you have a target psi in mind?
    thanks,

    Hello, the G-squared unit which is aluminum works from 50 to about 110 psi. They come with a miniture pump with a built in gauge. I used a metal tire valve stem extension and removed the threads so you did not have to thread it on and off losing pressure. G-squared makes the units for Joe at J.S. air cushion . Jeff
