Features

  • You can easily measure the circuit pressure up to 35MPa even during pressurization.
  • If you install a special nipple (APT-N-2) to the circuit requiring pressure measurement, you can check the pressure whenever required.
  • Cost reduction, by replacing the pressure gauge currently in use with this pressure tester.
  • You can read the pressure at all positions by connecting a high pressure nylon hose.
  • You can use this product when you want to vent air from the circuit and to sample hydraulic oil.
  • Easy diagnosis and maintenance of the hydraulic circuit.

Instruction for use

  • Use of the pressure tester must be limited to temporary pressure check. For use permanently subjected to circuit pressure, be sure to use our "NH hose" with pipe fittings.
  • The pressure tester hose is mainly made of nylon resin. Do not fold or twist it.
  • Special nipple
  • APT-N-※
images This is a check valve type special nipple to be mounted on the pressure detecting position. If you tighten the metal fitting on the high pressure hose side, the check valve will open.

  • High pressure hose
  • APT-※
images This is a high pressure hose to connect between the special nipple and glycerin pressure gauge. You can use it when the pressure detecting position is far separated from the place where you read the pressure gauge.

  • Pressure gauge adapter
  • APT-G-※
images Use this adapter when you want to connect the high pressure hose to the glycerin pressure gauge. Select the best adapter in conformance to the screw diameter of the glycerin pressure gauge to be used.
If you use this pressure gauge adapter, you can easily connect or disconnect the glycerin pressure gauge and high pressure hose by hand without using a wrench. Be sure to use this adapter for each of the glycerin pressure gauges you use.
