Pete's Plug® Brass 9/16"-18 Male UNF x 1.5" Length Temperature & Pressure Test Plug — Neoprene
The 311-562- Pete's Plug® is designed for systems requiring a 9/16"-18 male UNF connection rather than NPT. Its brass body and Neoprene self-sealing valve provide a reusable access point for pressure and temperature measurements.
The 1.5" body accepts a 1/8" probe. The straight UNF connection uses a Buna-N O-ring to provide the sealing interface specified for this configuration.
This model is a practical choice when equipment or existing test ports are designed around 9/16"-18 UNF threads.
Ideal for: Specialized HVAC equipment, industrial machinery, instrumentation connections, and equipment using 9/16"-18 UNF test ports.
Key specifications: 9/16"-18 male UNF; Buna-N O-ring; 1.5" brass body; Neoprene valve; 1/8" probe diameter.
