Model 350 Series
Hydrostatic Pressure Testing Tool
for Bottles and Cylinders
Pressures Up to 15,000 psi (1,034 bar)
The patented TestMaster® Model 350 Series Hydrostatic Pressure Testing Tool for Bottles and Cylinders offers fast coupling and positive sealing for production pressure testing of bottles, cylinders, tanks, and other components with an internally-threaded port.
The propriety collet design is the key feature of the Model 350 Tool. When the tool is engaged in the threaded area of the test piece, it does not mark or deform the threaded surface. This tool provides positive sealing on the end face of the internally-threaded port. Pressure compensation in the tool increases the sealing force, and ensures the collets remain engaged with the component threads, eliminating the need for additional safety devices. The tool can be used with a wide variety of services including water, oil, gas, or other liquids on request.
The Model 350 Series Tool is designed to meet your hydrostatic testing requirements. Configured for either manual or semi-automatic fluid testing, this tool integrates five technology patents for increased testing speed.
Benefits include: ease of use, faster rates of testing, higher quality assurances, and increased safety.
The Model 350 is suitable for hydrostatic pressure testing on bottles, cylinders, and tanks with standard working pressures up to 15,000 psi (1,034 bar) according to military, nuclear, automotive, and aerospace specifications, such as API, ASTM, ASME, ISO, DIN, and BS.
The Model 350 Series Tool handles standard and metric thread sizes from 0.50 in. to 0.88 in. ID (12.7 mm to 22.4 mm ID) major diameters.

Testimonial
Piper Metal Forming Corporation, a leading oxygen and carbon dioxide cylinder manufacturer, is among the first companies to realize the dramatic cost-saving benefits of the new Airmo TestMaster® Model 350 Series Hydrostatic Bottle and Cylinder Test Tool.
The TestMaster® Model 350 Series Test Tool solved Piper’s serious thread damage problem and product returns with its innovative collet design and self-seating piston actuation technology.
Piper Metal Forming uses a cold forging process to manufacture aluminum oxygen and carbon dioxide cylinders for the medical industry. Per US DOT compliance requirements, every cylinder that Piper ships must be tested before it leaves their manufacturing facility in New Albany, Mississippi.
Prior to installing twenty-four TestMaster® Model 350 Test Tools, Piper used a manual connector in their hydrostatic testing process that could damage cylinder threads when coupled and uncoupled. Damaged cylinders went undetected because they still passed the hydrostatic test and products were shipped without Piper knowledge. When a Piper customer realized the cylinder threads were defective, Piper replaced the cylinder adding to their manufacturing and shipping expenses.
Kyle Green, Senior Manufacturing Engineer at Piper, and the Airmo design team formed a strategic working partnership to custom design the TestMaster® Model 350 to meet the needs of Piper’s specific hydrostatic testing application.
Kyle Green, Piper Senior Manufacturing Engineer stated,
“We needed to eliminate thread damage on our oxygen cylinders and we did it. We have not had any products returned since January, 2008. We significantly reduced our scrap and at the current rate we see a payback on the twenty-four TestMaster® Model 350’s in less than two years. With the reduced scrap and no returns, our production rates should increase as well.”
Charles Smida, Airmo Inc. President said,
“It took some trial and error, but in the end we engineered the perfect solution for Piper. Currently, Piper Metal Forming is in the process of adding twenty-four more Airmo TestMaster® Model 350 Test Tools to their carbon dioxide bottle line.”
Harry Morán, Airmo COO replied,
“The TestMaster® Model 350 increases production rates, reduces scrap, and improves bottom line performance.
