Value Brand 1/2" Malleable Iron Tee Class 300

1/2" Malleable Iron Tee Class 300

This ZORO SELECT tee joins three 1/2-inch FNPT pipes in plumbing and compressed-air systems. Malleable iron construction meets ASME B 16.3, B 16.4, ASTM A-197 and ASTM A47 standards. FM Approved and UL Listed for code-compliant installations.

Sustained pressure and temperature performance

Rated for 2000 psi at 150 °F and 300 psi saturated steam, the fitting holds its seal across a -20 °F to 550 °F range. Class 300 wall thickness resists creep and thermal cycling better than lighter-class tees during long duty cycles.

Replaces Class 150 or lower-rated tees

Upgrade when system pressure exceeds 300 psi steam or 2000 psi water at 150 °F, or when codes demand FM and UL marks. Not for lines requiring larger bore, different thread type, or materials rated beyond 550 °F.
