TF420 Series Aluminum Alloy Handle Type Quick Connect Coupling
TF420 series quick connectors adopts eccentric handle clamping and are mostly used for manual low-voltage testing. It can realize
the pressure and Air tightness Testing of the parts to be tested with the outer diameter controlled straight pipe characteristics, as well as functional operations such as filling,
plugging and emptying. Such as sealing straight pipe outer wall,
flange pipe, fish scale pipe and external thread, etc.
TF420 quick connector achieves sealing by holding tight to the outer wall of the part to be tested through the front seal, so when in use, it must ensure that the surface of
the seal and the part to be tested is dry, if the sealing contact
surface is contaminated with water or oil and other lubricating
ingredients, the operating pressure can only be below 1 bar.
TF420 Quick Connector Advantages
1) Seal the straight pipe with small internal aperture.
2) Seal the straight pipe with wide tolerance range.
3) Sealing ring is self-adaptive.
4) No damage to the test pipe.
5) Simple operation, safe and reliable, easy maintenance.
TF420 Series Technical Parameters
| Applicable interface | Interfaces with the outer diameter controlled straight pipe characteristics: such as straight pipe
outer wall, flange pipe, fish scale pipe and external thread |
| Body material | Aluminum alloy, other materials can also be selected according to customer needs |
| Seal material | The main seal is made of nitrile rubber (NBR) by default, and other
materials can be selected according to customer requirements |
| Applicable medium | Dry, oil-free air or non-corrosive gas |
| Mode of operation | Eccentric handle clamping |
| Operating pressure | 0-3bar |
| Operating temperature | -15℃ - +100℃ |
| Leakage rate* | 10-4 Pa×m3/s |
* This is the minimum leakage rate of the standard products; We can provide devices with a lower leakage rate on demand; This depends on the detailed
specifications provided by the customer (test method, test
temperature and test pressure) and the quality of the sample
provided by the customer (i.e. the surface treatment of the sealing
surface, roughness and dimensional tolerances).
