Smartflow Stainless Steel Manifolds are made to last. Superior hand-welded construction and high quality stainless steel components create a reliable product on which industry depends in demanding applications. Industries served include: Military, Aerospace, Semiconductor, Plastics Injection Molding, Extrusion, Luxury Yachts and more.

Smartflow Stainless Steel Manifolds are available in standard and custom sizes. If we don’t stock what you need, contact us with your concept, sketch or fully detailed drawing.

Conventional Stainless Steel Manifolds

Conventional Stainless Steel Manifolds have a more robust construction with half-couplings welded to the tubing to form each port. These are recommended for manifolds that experience multiple changes to fittings or couplings. Other port and inlet sizes are available on a custom basis. Please call or email for information.

  • Inlet Sizes: 3/4", 1", 1-1/4", 1-1/2", 2" NPT or BSP
  • Port Sizes: 1/8", 1/4", 3/8", 1/2", 3/4" NPT or BSP
Low-Profile Stainless Steel Manifolds
  • Inlet Sizes: 1", 1-1/2" NPT or BSP
  • Port Sizes: 1/4", 3/8", 1/2" NPT only, internal manifold ports

Low-Profile Stainless Steel Manifolds are a more economical option. NPT ports are formed into the tubing. British threads are not available in the low profile manifold. This option is recommended where ball valves or fittings will be permanently installed into the ports without future change.

High Pressure and Temperature Stainless Steel Manifolds Smartflow High Pressure and Temperature Manifolds and Assemblies are designed for use in pressurized hot water cooling systems up to 450°F (232°C), 450psi (31bar) and hot oil cooling systems up to 600°F (315°C), 100psi (6.9bar)

Smartflow manifolds are ideal for connection to temperature control units in an injection molding environment. The manifolds are available with 1" and 1-1/2" inlet sizes (one end only). Optional Flowmeters and regulators are constructed of stainless steel with high temperature seals for corrosion-free operation and long trouble-free service life.
