A 3/4-inch 316 stainless steel cross fitting rated for 150 psi threaded heavy-duty service

  • 3/4 inch threaded cross connects four pipe runs

  • Heavy pattern design provides extra wall thickness for durability
  • Zoro Select brand ensures consistent manufacturing quality

Industrial Cross Fitting

The Zoro Select 3/4 inch cross connects four pipe runs in a single junction. Rated for 150 pressure class and made from 316 stainless steel, it suits corrosive fluid handling in industrial plumbing systems. Threaded heavy-wall ends allow direct assembly without welding.

Sustained Pressure Performance

The 316 stainless construction resists chemical attack and maintains seal integrity during continuous pressurised service. Heavy-thread engagement distributes mechanical stress evenly across the fitting body, reducing the risk of fatigue failure under cyclic loading.

Pre-Installation Checks

Verify that the mating pipe schedule matches the heavy-thread profile to ensure full thread engagement. Confirm the system design pressure does not exceed the 150 class rating and that the 316 alloy is compatible with the process media.

Questions about this item

Does the 316 stainless cross generate heat or noise when fluid runs through it all day?

The fitting is a passive 316 stainless component with no moving parts, so it produces no noise and adds no heat beyond the fluid temperature.

What pipe size and thread type must my existing lines have to connect to this cross?

It requires 3/4 inch threaded pipe ends that match the cross's heavy-thread pattern for a secure seal.

Will the 150 pressure-class cross hold up when mixed with older Schedule 40 piping in the same system?

The cross is rated for 150 psi service, which aligns with standard Schedule 40 ratings, so it can remain in the same line without creating a pressure weak point.
