SprayTech part 975-304 is a 4-gun 3/8" manifold designed to distribute fluid flow to multiple spray guns on compatible airless sprayers. This component enables simultaneous operation of up to four spray guns by evenly splitting fluid output, supporting increased productivity and large-area coverage. It helps maintain balanced pressure, ensures consistent material delivery, and supports reliable multi-gun performance. This part restores proper flow distribution and efficient system operation on compatible units.

The SprayTech 975-304 4-gun 3/8" manifold is designed to enable multi-gun operation by distributing fluid from a single sprayer to up to four spray guns simultaneously. On compatible systems such as 0528925N 2000 4000, Admiral, Commander, Hydra M and Hydra Pro Super, and Hydra M and Hydra Pro 2000 4000 models, this manifold plays a critical role in maintaining balanced flow and consistent pressure across all output lines. It allows operators to significantly increase productivity by covering large surfaces more efficiently while maintaining uniform spray performance. The manifold is engineered to handle high-pressure fluid delivery while minimizing pressure drop and ensuring even distribution to each connected gun. Over time, manifolds may experience internal wear, blockage, or fitting degradation, which can result in uneven output or reduced system efficiency. Replacing the manifold restores proper flow balance, improves operational consistency, and supports reliable multi-gun performance in demanding applications.
A worn or damaged manifold may cause uneven fluid distribution, pressure imbalance, or leaks. Replacing this component helps restore proper flow control and consistent operation.
