Abstract
A fluid manifold includes at least two releasably interconnected modules, a valve assembly being mountable on each module. A fluid supply channel in each module is in fluid communication with the valve assembly thereon and with fluid supply channels in adjacent modules. A seal assembly provided between adjacent modules prevents leakage of fluid from the supply channels. Each module has two recesses at one end and two outwardly projecting and integral arms at the other end which are received in the recesses on an adjacent module. The arms and recesses have cooperating detents which retain the modules in the interconnected relationship, and screws extend into grooves provided on the arms to maintain the modules locked together.
