Operating principle
- Optimizes life and prevents wear of CUPLA by absorbing strong shocks generated by connected vibrating tools.
- Prevents hard-to-notice flow reduction caused by CUPLA wear under continuous vibration.
- Flexible rubber hose allows free and wide range of tool motion.
- Protects CUPLA from shock generated by vibrating tools and impact tools.

Choose the ANTI-VIBRATION PLUG HOSE when a vibrating or percussive air tool runs at up to 1.5 MPa {15 kgf/cm2} and the coupling itself has to be kept away from the shock: it is an intermediate hose carrying a HI CUPLA Plug 30PH, not a coupling mounted directly on the tool. The one-way shut-off sibling series in this group, such as HI CUPLA BL, LOCK CUPLA 200 or ROTARY PLUG, carry the same 1.5 MPa {15 kgf/cm2} rating but connect the tool directly. Where the fluid has to be held on both sides at disconnection, take a two-way shut-off series such as COMPACT ZEROSPILL CUPLA, which is rated 1.0 MPa {10 kgf/cm2}.
