Description
Lines that are parted and remade during operation cost time when they are screwed together. The Nitto Kohki High Flow Cupla joins hose and pipe lines by hand and is available in the HFL-2, HFL-3 and HFL-4 sizes.
- Connected and disconnected by hand, with no tools and without undoing a threaded joint
- Coupling body in brass or in stainless steel, matched to the surroundings and to the medium
- Seals in FKM or EPDM, so the material pairing suits the medium being carried
- HFL-2, HFL-3 and HFL-4 sizes cover different line cross sections within one series
- Socket and plug are available separately, so a damaged part can be replaced without renewing the whole connection

Operating principle
- Both socket and plug have built-in automatic shut-off valves.
- High flow rate type to increase cooling effect.
- Quick connection and disconnection of cooling pipes.
- Compact and space-saving design. Compared with the coupled length of SP CUPLA type A, that of HI FLOW CUPLA is reduced by 22%.
- Installation and maintenance can be done within a short time.
- BI Type: easy connection with stainless steel pipe.
- BI Type: connection to plastic hose is possible with optional hose connection kit.
- BI Type: connection to various tubes is also possible via the use of appropriate optional inserts.

| PURGE HI CUPLA | 15 bar | PVR Type: thread 1/2 inch, 3/4 inch, 1 inch; hose barb 1/2 inch, 3/4 inch, 1 inch hose. PV Type: thread 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch | One-way shut-off | Air |
Pick HI FLOW CUPLA when the cooling or temperature control line has to be closed on both sides, since every peer series in this group except COMPACT ZEROSPILL CUPLA is one-way shut-off. Against COMPACT ZEROSPILL CUPLA, which is also rated 1.0 MPa {10 kgf/cm2} and two-way shut-off, HI FLOW CUPLA is the high flow rate version with a coupled length 22% shorter than SP CUPLA type A. Where the line runs at 1.5 MPa {15 kgf/cm2}, HI CUPLA BL, LOCK CUPLA 200 or the other one-way shut-off series carry the higher pressure.
