Junioseal is able to provide safe, dimensionally and functionally interchangeable subsea wellhead, mudline and tree equipment within the scope of API. The performance requirement of pressure integrity, thermal integrity, material choice along with no observable leakage allowable are met with these sealing desires. The Junio-240SBX Ring Type Joint is the same design as the BX Ring, however the suffix S indicates that additional pressure equalisation holes have been drilled to prevent pressure lock in accordance with API 17D for use on subsea wellhead and christmas tree equipment.
