Pete's PlugsĀ® allow you to take pressure and temperature readings quickly without leaving costly gauges on the line
- Quickly take a temperature or pressure reading
- Self closing Neoprene or Nordel valves after probe removed
- Cap to protect and additional seal
- 1/8ā, ¼ā, 3/8" & ½ā NPT pipe connections
- 9/16ā & 3/4ā UNF pipe connections with Buna-N O-Ring
- For 1/16ā & 1/8ā probes
- Brass or Stainless-Steel housing
Neoprene Valve (blue strap) resists waxes, fats, oils, greases, petroleum products, and most refrigerants. Can be used for natural gas applications.
Nordel Valve (yellow strap) is an ethylene-propylene based synthetic rubber for hot and cold water, low steam, detergents, phosphate esters, ketone, alcohols, and glycols.
NPT - National Pipe Thread Tapered threading for sealing for connection in nearly every type of service. Use a sealing compound for a leak-proof joint.
UNF - Unified National Fine a fine-threaded straight (not tapered) pipe thread for high precision, tight connections with an o-ring for complete sealant.
BSP - British Standard Pipe Threading (metric dimensions) An appropriate sealing compound can be used in the thread to ensure a leakproof joint. It is a standard screw thread type that has been adopted worldwide, except in the U.S. where NPT is standard.
This information is a general guide on Pete's pressure and temperature test plug II and the product should be tested for applicability under actual conditions.
