Pete's Plug® Brass 9/16"-18 Male UNF x 1.5" Length Temperature & Pressure Test Plug — Nordel
The 311-572- Pete's Plug® provides a 9/16"-18 male UNF connection for equipment requiring a fine-thread test connection, combined with a brass body and Nordel self-sealing valve.

Ideal for: Specialized HVAC equipment, industrial systems, hydronic equipment, and machinery using 9/16"-18 UNF test connections.
Key specifications: 9/16"-18 male UNF; Buna-N O-ring; 1.5" brass body; Nordel valve; 1/8" probe diameter.
