What if some older farm tractors, use quick couplings that do not meet ISO standards?
It is true that some older models of agricultural machinery and tractors use quick release couplings that do not meet ISO standards. We have custom made quick release couplings for some older tractor models to replace their broken quick release couplings. For example, John Deere, International Harvester, and Case. You can send a sample to our factory and we can customize any old model directly for you. This solves the problem of not being able to find quick release couplings for older models.
What is the difference between push-pull quick release couplings and normal ISO 5675 quick release couplings?
The sleeve of push-pull quick coupling can move in two directions. The process of connecting and disconnecting the quick coupling can be achieved by operating the sleeve in the inward and outward directions. With a normal ISO 5675 quick coupling, the sleeve needs to be pushed in one direction before the male coupler can be pushed into the female coupler during connection. When the sleeve is released, the steel balls will be locked by the sleeve to complete the connection process. Although the operation is equally simple, it is not as easy as the push-pull quick coupling, where the hose containing the female is connected by pushing in one direction and then disconnected by pulling outward together. Therefore the push-pull type is much easier to operate.
Is it possible to replace existing quick couplings with flat quick couplings on agricultural machinery?
Usually, it is possible to replace the existing quick coupling with a flat face quick coupling, which can replace the existing quick coupling in terms of flow rate and working pressure. However, when it comes to the threaded connection, especially when some quick couplings need to pass through the bulkhead, special attention should be paid to the dimensions of the flat quick coupling. You can consult us to find out if the replacement is possible.
What is the difference between a ball valve and a poppet valve?
We often come across ISO5675 quick couplings where we see ball valves and poppet valves, and generally, users will look for replacement quick couplings based on the original factory-equipped quick couplings. Sometimes some users will ask the difference between a ball valve and a poppet valve. In fact, in most parameters, there is no difference between ball valves and poppet valves. However, the ball valve does not use a seal ring to achieve the sealing effect, but the deformation between the ball and the quick coupling shell to achieve the sealing effect, so when the pressure is low, there may be some dripping phenomenon. But the ball valve also has the advantage that it will not be affected by seal damage, working temperature, etc.
