LEH - X64 Range - Series 764

One-hand operated

LEH Series 764 is a Flat-Face quick-connect nipple with a built-in pressure eliminator. The nipple is according to and exceeds the demands in the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The pressure eliminator allows for connection with residual/trapped pressure on the nipple side. The nipple Series 764 connects with couplings in Series 765 and Series 766.

The pressure eliminator nipples are also available in four smaller sizes; 1/4" / DN 6.3 (Series 264), 3/8" / DN 10 (Series 364), 1/2" / DN 12.5 (Series 564) and 5/8" / DN 16 (Series 664). For steel couplings in accordance with ISO 16028 see Series 765. Stainless steel versions of the standard are available in Series 766.
