Steel type (carbon steel)
| Fluid used |  General hydraulic oil |  Water |  Chemicals |
|---|---|---|---|
| Operating temperature limit | Seal material NBR ：-30℃～ +93℃ EPDM ：-54℃～ +149℃ Fluorine rubber：-30℃～ +190℃ | ||
| Maximum working pressure | 7.0～ 45.0MPa | ||
The possibility of large spills exist do the high volume that can pass through the system.
The PH type has a bult-in “PH valve” that can be easily connected to relieve residual pressure.
Sealing materials is prepared for 3 types: NBR, EPDM and FKM. (but PH type is NBR only.)
Sleeve lock mechanism is possible to make the existing connection more secure by rotating the sleeve and moving the slit away from the lock-pin.
