VU4 4 - Corner Manifold (NPT)

Four corners. Four ports. One block. The manifold is where an air system stops being a set of parts and starts being a suspension. It is the piece that decides how fast a corner fills; how cleanly it holds and whether the truck is still level in the morning. The VU4 runs four corners independently through all stainless steel valve components in a machined block that measures 5.28 inch by 2.75 inch by 2.75 inch. The internal architecture is built for flow and for bubble-tight sealing; Accuair publishes operation to 200 psi for millions of cycles. Every port is 1/4 inch NPT. That is a thread you can buy a fitting for anywhere; no proprietary connection between you and a line. It lives under the vehicle where the weather is. That is what the sealed construction and the weather-proof connector are for.

  • Four corners; four independent circuits - each bag fills and dumps on its own so the truck can be levelled rather than just raised.
  • Stainless valve components - the parts that cycle millions of times are the parts that should not corrode.
  • 200 psi rated - published for operation at full system pressure rather than near it.
  • Standard 1/4 inch NPT ports - fittings you can source anywhere instead of a proprietary connection.
  • Compact block - 5.28 inch by 2.75 inch by 2.75 inch fits behind a wheel tub or under a bed floor.
  • Built for under the vehicle - sealed construction and a weather-proof connector for the environment it actually lives in.

AccuAir knows the importance of a high quality valve manifold and that is why we have developed the VU4 valve manifolds for your air suspension systems. This VU4 valve manifold is a 4 corner manifold, meaning that it is designed to inflate and deflate 4 individual air springs. The VU4 manifold is outfitted with ¼” NPT fittings on all ports for easy installation of your air suspension system plumbing.

At AccuAir, we are all about ease of installation and keeping things clean. On the VU4 manifolds, you will get a high-quality, weather-proof plug-n-play harness to help make your installation quick and get accurate wire connections built to last in the harsh under-vehicle environment. To add to the already high-quality construction, each of these valve manifolds will feature all stainless steel valve components. The robust internal solenoid valve architecture maximizes flow rates, provides bubble-tight sealing, and guarantees operation up to 200 psi for millions of cycles. These manifolds help to provide the cleanest installation possible while delivering the most reliable operation on the market today. Pick up one of the AccuAir VU series valve manifolds for your air suspension system and make installation quick and easy.

Overall size of the VU4 4-Corner Manifold (NPT): 5.28" x 2.75" x 2.75"

What Are Air Manifolds In Air Suspension?

A valve manifold for air suspension is the heart of any air suspension system. The valve manifold electronically controls the air delivery in your system. It is usually made up of an aluminum block with electronic solenoids, valves, and ¼” fittings to allow for an easy installation. The biggest thing to look for here is whether you need a 2 or 4 corner unit, the quality of the manifold as it may be exposed to the elements, and the way that it connects to your system.

Universal air management component. This manifold is defined by the system it controls rather than by the chassis it mounts to.
Four corner air suspension builds running independent control of each air spring.
All ports are 1/4 inch NPT so standard fittings apply - the AA-3649 swivel elbow and AA-3655 straight are both that size.
No Gen: tag and no vehicle application is published on this listing; generations are left blank rather than guessed.
