Ralston Instruments Hose and Adapter Kits

Adapters have a unique sealing system that makes them excellent for both high and low pressure calibration.
  • ABS case with foam cut-outs makes it easy to see if any adapters are missing
  • Adapters are available in kits or individually.
Kits take the guesswork out of selecting adapters by providing a selection of the most popular combinations of hoses and adapters necessary to connect to any pressure transmitter, gauge, hand pump, manifold or nitrogen source. Use the individual hoses and fittings to connect to any device you will be calibrating.
