Check the full thread depth of the internal threaded female port as well as the stud length of the external threads male on the fitting. Ensure that the internal port depth is longer than the port stud length. When it comes to port sealing, there are usually not easy solutions to leaks.
While the solution may not be easy, investigating what may be going wrong is not as difficult as you may think. With either of these, the outlook is not good, but at least you have an answer to your troubleshooting question and know what you need to do to fix the leak. If you have any questions or comments, please post them, and we will respond if warranted.

Leaking Ports? April 23, by TechConnect Team. Once you depressurize and lock-out your system, there are two important aspects to consider when troubleshooting your port: First, check the internal threads also called female of the port. Is it in good working order or is it damaged?
Here are five factors to consider when you're searching for the right fitting:. At RG Group, we carry a large selection of Parker high pressure fittings and adapters to meet your needs. The types of fittings available include:. Parker is a global leader in control and motion technologies, with more than years of engineering success in a wide range of industries.

The issue is that you would now lose the traceability because there would not be any external identification mark to indicate that it is an ISO assembly. This may cause problems when the fitting connection requires servicing and is possibly misidentified as a result. Though the threads are the same, this will not provide a reliable seal.
No sealing method should ever have two elastomers coming into direct contact with each other. The two elastomer surfaces coming in contact may allow fluid to seep through. The Type E fitting is designed to accommodate the trapezoidal seal and not the round cross section O-ring.
The Type E style port is designed for spotface sealing. Therefore, if a round cross sectioned O-ring was added instead of the trapezoidal elastomer, the face would not be able to compress the O-ring completely into the gland of the ISO port.
This would cause a gap between the two sealing surfaces creating a connection that leaks. This is similar to the third example above except the groove in this fitting was designed for the volume of a trapezoidal seal. Placing a round cross section O-ring in this groove would not fill the groove correctly, causing a potential leak. There is a significant amount of knowledge that is behind how these fittings are designed to function.
Understanding the content in this post should clear up some of the confusion about how these two styles of ports differ. This can also act as a quick reference piece for you and your co-workers when questions arise. With these differences now made clear, decisions about which metric fitting goes with which metric port can be made with confidence.

Figure 3b — ISO adjustable stud end identifying marker These identification marks will still be clearly visible, even once the fitting is fully assembled.
These styles utilize a seal with an elastomer bonded to the ID of a metal ring 4 Type A — Applies to fixed studs only. This style utilizes a soft metal seal, typically made of a soft material such as copper 5 Type B - Applies to fixed studs only.
