Maximum gap minimization is achieved by optimal application of the geometric principle of the taper. Existing standards and specifications will be examined to show how the protocol is iiso applicable, and recommendations made to adequately cover the intent of the official testing protocol.

Request a copy of the Test. Plug can be resealed repeatedly without loss of effectiveness.


E Program In Print Links. 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. Request An Engineering Packet. Evaluation by the FPI determined the maximum pressure that each specimen could withstand before it would no longer contain the fluid. 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.


EPCO wanted confirmation of these values under accepted industry practices and established measuring methods.

The paper will discuss testing methods for a new style of fittings. The Zero-Leak Gold Plugs provide a primary metal-to-metal seal with an independent elastomeric back-up seal. Zero-Leak Gold plugs are interchangeable with standard port entry plugs.

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. This defines a failure. Three samples of plug fittings, sizes ranging from to —12, were torqued to a percentage of prior test results.

The fittings developed a zero leak seal at lower assembly torque values than their SAE counterparts. Testing was performed on plug sizes —02 through —12, testing 3 samples of each respective 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.


New and revolutionary designs in fittings, sometimes, do not apply to stated standards and protocol for testing. Additional testing will be conducted to determine Proof and failure pressure of the plugs. Effective in vibration, temperature variation, and pressure spike situations.

Some additional benefits of using this type of plug are: The purpose of the test is 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.

Once the minimum torque value had been established for each plug size a 2,cycle endurance test was performed on each selected plug size.
