Handle Type Quick Connector TF421 (High Pressure Application)
TF421 series quick connector adopts eccentric handle clamping,
which is mostly used for manual high-voltage test. It can realize
the pressure and Air tightness Testing of the parts to be tested with the internal diameter controlled straight pipe characteristics, as well as functional
operations such as filling, plugging and emptying. Such as sealing
the outer wall of the straight pipe, flange pipe, fish scale pipe
and external thread.
TF421 quick connector achieves sealing by holding tight to the outer wall of the parts to be measured through its front seal, after the grooved jaw is retracted, it firmly hold the outer wall of the part to be measured, so the operating pressure can reach 70bar.
TF421 Quick Connector Advantages
1) The operating pressure is high, which can reach 70bar.
2) Seal the straight pipe with wide tolerance range.
3) Sealing ring is self-adaptive.
4) Simple operation, safe and reliable, easy maintenance.
TF421 Series Technical Parameters
| Applicable interface | Interfaces with 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 | Regular fluid or non-corrosive gas |
| Mode of operation | Eccentric handle clamping |
| Operating pressure | 0-70bar |
| 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).
