Flexible Pressure Tubing and Adapters from Ralston

Quick Test Hose assemblies can be furnished in any length with either a knurled brass nut and probe end or a stainless steel 1/4" stub end. The hose has an extremely small diameter (.070"), is very flexible and has a very high pressure rating (6900 psi). This flexibility, light weight and high rating make it ideal when high pressure must be transmitted for calibration.

The knurled brass ends utilize a unique 'O' ring seal to make a fingertight-pressuretight connection to our series of hose adaptors.  Adapters are available for all NPT sizes.  In addition a NEW fingertight calibration fitting is available so you can simply screw in a device to be calibrated (such as a pressure gauge or transmitter) without the use of wrenches!  Perform a full calibration without any teflon tape, pipe dope or tools!.

The stainless steel tube stub allows you to swage on your own ferrules and nut for wrench-tight connection to tube fittings. Both types of hose end are reinforced with a tension relief spring.

	Finger tight to 6900 psi!
	Standard and custom lengths available
	Safety regulator to protect test devices
	Finger tight test connections also available

Pressure Pumps from SI Instruments

SI Instruments offers (3) pump models to handle pressures from vacuum to 10,000 psi

1.  The TP1-40 generates pressure up to 600 psi OR vacuum to -29”Hg. Made with no plastic parts these pumps are designed to endure harsh environments unlike competitor’s disposable models.  These pumps are ideal for use with electronic calibrators, digital indicators, analog gauges, pressure transmitters, transducers, relief valves, or similar instrumentation. Our pumps are the most efficient pumps on the market with the fewest strokes to maximum pressure.

2.  HTP1: For water/hydraulic pressures up to 15,000 psi

3. LTP1: Controls pressures from vacuum to 30 psi, offering extremely fine resolution for low pressure devices including inches-of-water transmitters/gauges. 0.00145 psi sensitivity.

Pumps can be purchased independently, or in a kit including carrying case, NPT adapters, seals and hoses.

	Both pressure and vacuum in one pump!
	600 psi pressure/-29" Hg, TP1-40
	15,000 psi, HTP1
	vacuum to 30 psi, LTP1

‘Orion’ Pneumatic Pressure Controllers from Condec

The Orion Pneumatic Pressure Controllers are variable volume pressure controllers. They consist of two low torque, fine micrometering valves with positive shut off, adjustable stop and soft seat. The Orion is ideal for manual pressure device calibration in the laboratory or on a mobile calibration cart. Valves for gas inlet, gas exhaust and fine pressure control are included. Use the Orion with either the DLR334 or RPM3 pressure indicator detailed below.

Orion 2C for pressures to 3000 psi

Orion 3A for pressures to 10,000 psi

	Adjustable stop means valves can not be over-tightened!
	Two output pressure ports can connection to standard and test device.

GaugeCal XP from Crystal Engineering

The GaugeCaLXP is a self contained, precision hydraulic pressure comparator intended for the calibration of pressure gauges rated up to 700 bar or 10,000 PSI.

Two pressure ports are provided. Connect a reference grade gauge on one port (we recommend an XP2i Digital Pressure Gauge from Crystal Engineering) and the gauge to be tested on the second port. Rotate the handle clockwise until the desired pressure is generated. Then, compare the displayed pressure values between the reference gauge and the gauge under test.

Pressure can be set very quickly and precisely. Gauges can be calibrated in less than ten minutes with 5 to 10 test points, increasing and decreasing pressure. The comparator can be filled with your choice of fluid: water, oil, or isopropyl alcohol.

	Manual pressure control up to 10,000 psi
	Self-contained pressure generation
	Use with water, oil, or isopropyl alcohol.
	Ideal for use with XP2 digital standard (see digital indicators section of website)
	Pricing from $1495
