Note

All foreline traps manufactured by KEY HIGH are available with the option of a 1/8" female NPT port. Typically the port is located on the bottom of the trap and is used to install thermocouple gauges, drain cocks, etc. Add -1/8FNPT to suffix of trap part number and e-mail a sketch showing the required location. There is a nominal $ 65.00 charge for each requested port and all ports are "plugged" with a stainless steel male NPT plug before shipment.
