EPCO wanted to determine more accurately the burst pressures of the larger and smaller plug sizes that were not originally included in the earlier Zero-Leak Gold Plug tests conducted by the Fluid Power Institute.
Request a copy of the Test. Zero-Leak Gold plugs are interchangeable with standard port entry plugs. Existing standards and specifications will be examined to show how the protocol is not applicable, and recommendations made to adequately cover the intent of the official testing protocol.
Three samples of plug fittings, sizes ranging from to —12, were torqued to a percentage of prior test results. The paper will discuss testing methods for a new style of fittings.
New and revolutionary designs in fittings, sometimes, do not apply to stated standards and protocol for testing. Plug can be resealed repeatedly without loss of effectiveness. E Program In Print Links. Evaluation isp the FPI determined the maximum pressure that each specimen could withstand before it would no longer contain the fluid.

This defines a failure. EPCO wanted confirmation of these values under accepted industry practices and established measuring methods.
Effective in vibration, temperature variation, and pressure spike situations. The fittings developed a zero leak seal at lower assembly torque values than their SAE counterparts. Once the minimum torque value had been established for each plug size a 2,cycle endurance test was performed on each selected plug size.

Zero-Leak Gold Plugs have been identified as a replacement and improvement to the standard hollow hexagon plugs manufactured to SAE J presently used within current end fitting terminations. The fittings developed a zero leak seal at very low assembly torque values and EPCO wanted to determine more accurately the torque values at which the fittings would not leak under accepted industry practices and established measuring methods.
With the plug fittings at their minimum torque values they must complete a 1,cycle pressure fatigue test in accordance to NFPA fatigue standard T2. The purpose of the test 1463-1 to prove the integrity of the Zero-Leak Gold plugs when independently subjected to both internal and external pressure.
Hydraulics and Pneumatics at work in your world. Testing was performed on plug sizes —02 through —12, testing 3 samples of each respective size.

The Zero-Leak Gold Plugs provide a primary metal-to-metal seal with an independent elastomeric back-up seal.
Request An Engineering Packet. Additional testing will be conducted to determine Proof and failure pressure of the plugs.
Some additional benefits of using this type of plug are: Maximum gap minimization is achieved by optimal application of the geometric principle of the taper.
