Value Brand

Value Brand 1-1/2 in Socket Weld Union 304 Stainless Steel Class 3000

SKU CH-449C-MF8P1

A 304 stainless steel socket weld union joining two 1-1/2 inch pipes with a Class 3000 pressure rating

  • 304 stainless steel resists corrosion in demanding piping systems
  • Three-piece union design joins 1-1/2 in pipe ends without rotation
  • Class 3000 rating handles 2,900 psi at 100°F working pressure
  • Steam service rated to 2,500 psi at 350°F operating temperature
  • Meets ASTM A182 and MSS SP-83 standards for pressure-tight sealing

Socket-weld union for 1-1/2 inch pipe

The Zoro Select 1LUH8 joins two 1-1/2 inch pipe ends without requiring pipe rotation. Its three-piece design uses a body, nut and mating seat to create a pressure-tight seal. The fitting is manufactured from 304 stainless steel for corrosion resistance. It meets ASTM-A-182 and MSS SP-83 standards for specified operating conditions.

Socket weld connections with female ends

Both ends feature socket weld connections with female gender fittings and an 11 1/2 pipe threading specification. This configuration allows direct welding into the piping system while the union nut enables straightforward disassembly for maintenance. The design frees installers from the need to rotate pipe sections during assembly or removal.

Upgrade from threaded or flanged joints

This union replaces threaded couplings that demand pipe turning or flanged connections that add bulk and bolt hardware. The jump is worth it when a system requires frequent separation for service, vibration resistance or a compact joint rated to 2,900 psi at 100°F and 2,500 psi steam at 350°F. Buyers needing larger diameters or different pressure classes cannot use this fitting.

Questions about this item

What pressure limit appears first during continuous operation?

The 2,900 psi rating at 100°F is the primary pressure ceiling; steam service is limited to 2,500 psi at 350°F.

How does the fitting behave thermally during all-day service?

304 stainless steel conducts heat, so the union will reach fluid temperature; no insulation is included.

What pipe preparation is required before welding this union?

Both ends are socket-weld female for 1-1/2 inch nominal pipe; the pipe schedule must suit Class 3000 service.
