It is a widely known fact that O-ring face seals help prevent leaks in various hydraulic applications with the help of O-Ring Face Seal fittings. However, these kinds of fittings should abide by SAE J1453 standard. They are manufactured from nickel-plated carbon, carbon, or stainless steel.

An Overview 

Talking about the most commonly used type, ORFS fittings like Viton, Buna-N, or 90 Durometer rings that would be a perfect seat into a groove in the fittings face. USually, seals are generated whenever the O Ring is pressed into the flat face of the female machine which is similar to split flange type of fittings. Whenever the connection is tightened, the rings get suppressed against the sleeve of the flat face which is situated at the end of the tube. This helps create a metal to metal seal.

So, these flat face O-Rings are also termed as elastomeric seals. They are very common in hydraulic as well as tube applications. Elastomer seals are a kind of rubber-like seal. Since this is a rubber-like seal, it essentially would be leakproof. However, ORFS fittings can easily help in preventing hydraulic system leaks having operating systems as high as around six thousand PSI. 

Truly Effective In Leakage Elimination

ORFS fittings have been truly efficient in eliminating as well as preventing leaks in hydraulic systems having operating pressures as high as six thousand PSI as mentioned earlier. The O-Ring Face Seal fittings are designed in such a way for different applications in which elastomeric seals are used to deal with the leakage and the changing situations in the processes of assembly. However, the fittings are supposed to be connected to timing grades with the help of silver brazing. Additionally, these fittings can be reassembled as well as disassembled in the respective field. This would be carried out to promote O ring replacement or even the complete assembly. 

Why Does This Hydraulic System Leakage Occur?

ORFS has been reliable against the system leakage in the hydraulic connections. However, poor-fitting might be the cause of the leakage in the hydraulic applications. Additionally, poor system design, low-quality components, and inappropriate installation are some of the major factors that are responsible for the leakage. 

Owing to these faults in the system, the outcome can be costly. It is not just restrained to the downtime or the equipment, but the fluid loss would be very substantial. Hence it becomes very important to not just incorporate ORFS fittings but also look for other measures of the system. 

If the above-mentioned measures are strictly followed and checked with the time, there would be no consequence of leakage. 

ORFS fittings have been very popular in onboard off-road vehicles in hydraulic lines that include heavy equipment used for the construction. These fittings abide by some standards that take care of all threads, dimensions, fitting, and performance requirements for use in hydraulic applications.  The biggest advantage of ORFS fittings is the manufacturers extend the warranty period of the equipment since the fittings deliver very low leak points.
