AccuAir’s VU4 Manifold has become an industry standard. Backed by a lifetime warranty and solid reliability, it’s hard to beat. This electronic solenoid valve unit inflates and deflates up to four (4) individual air springs and has built-in, DOT approved, 3/8” PTC ports for all of its plumbing connections. Although the VU4 may look pretty, it’s durable enough to survive the harsh under vehicle environments. The wires from each of the solenoids route to a single weatherproof connector, eliminating typical loose wires. This manifold can be used with most managements and system configurations.
