Product Details

The Firstco 9KT-PST01 is a refrigerant piston metering kit designed for use with First Co. fan coil units and air handlers operating in the 18,000 to 36,000 BTU/H (18k–36k Btuh) capacity range. This fixed-orifice metering device provides precise refrigerant flow control at the indoor coil, serving as a cost-effective alternative to a thermostatic expansion valve (TXV) in compatible split-system cooling and heat pump applications.

Key Features:

  • Fixed-orifice piston-type refrigerant metering device
  • Compatible with First Co. air handlers and fan coil units rated 18,000–36,000 BTU/H
  • Designed for use with R-410A refrigerant systems
  • Provides reliable, passive refrigerant flow metering without moving parts
  • OEM replacement part manufactured to First Co. specifications
  • Suitable for field installation in new or replacement applications

The 9KT-PST01 piston kit is a genuine First Co. OEM replacement component, ensuring proper system performance and compatibility with matched outdoor condensing units and heat pumps. Selecting the correctly sized piston for your system's capacity is critical for efficient operation and optimal refrigerant charge balance.

Fast shipping! Didn't know what to expect because I had never shopped here before but was very impressed.

Product was excellent

First time customer and very pleased with price and service.

It was delivered when it said it was supposed to haven't opened it yet but look forward to seeing it

Easy to navigate the ordering process and received the product in a timely manner.

This was one of the few places I could find that had these in stock.

Thank you

Thank you

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.
