A fastener assembly including an elongate fastener adapted to extend through a chamber having a longitudinal axis, a first end and a second end; a first seal disposed at least partially at the first end of the fastener to prevent leakage of fluid from the chamber; and a second seal disposed at least partially at the second end of the fastener to prevent leakage of fluid from the chamber. In a specific embodiment, the first and second seals are conical seals and a third seal is provided by a gasket. The invention also provides a method for securing a fluid filled chamber to a surface comprising the steps of: placing an insert onto the surface such that a first end of the insert abuts the surface; placing the chamber onto the surface whereby the insert extends through an opening therethrough; threading a first end of a threaded fastener through the insert into the surface thereby closing a first lower seal arrangement; and securing the chamber to the surface by sealing the chamber with a nut thereby closing a second seal arrangement with respect to the chamber.
