PRESSURE TEST PLUGS

Weiss Temperature/Pressure Plugs allows for quick, efficient and accurate testing of
hydronic pipe lines throughout HVAC systems. Offered in both nordel (blue cap) for
hot and chilled water and neoprene (red cap) for natural gas. Weiss plugs are consistently
rated at 1000 psi. The self-sealing core insures long life and continuous service.
