Introduction: The O-ring and retainer ring structure can withstand much more pressure than when using an O-ring alone. The Parker retaining ring can be said to supplement the pressure seal and is not itself a seal. The main reason for using the retaining ring is to reduce the clearance on the low pressure side of the O-ring and similar seals.
The Parker retainer is molded from a high-hardness rubber material into an uninterrupted ring that can be easily assembled by stretching. Since it is neither cut nor spiral, it does not cause local damage to the O-ring. It can be said that the two are a natural match.
Experiments have shown that Parker's retaining ring has a longer life and higher reliability than other types of retaining rings. The existence of the retaining ring allows the O-ring to expand the working pressure range, and there is also a small amount of lubricating oil between the two, which increases the lubrication and makes it easier for the two to get along.
The profile design of the Parker retainer ring improves the performance. This structure allows the O-ring to remain circular even under high pressure. With the appropriate groove structure, the retainer ring will not collapse and never cool into the gap. . It can be said that the retaining ring is the "optimal patron saint" of the O-ring.
The continuous structure of the Parker retaining ring means that it does not cause the O-ring to squeeze out, crumble or bite like a notched, spiral, or other discontinuous structure, reducing the O-ring because of cutting, tearing and not right The chances are therefore more reliable and extend the life of the O-ring. It can be said that the two hand in hand to whiteheads.
Parker O-Rings + Parker Retaining Rings are more eye-catching in the performance of dynamic seals, and sometimes a small change can make the problem perfect.
