3/8″ Wing Style Nipple, 3/8″ NPTF Brass (101115-3) Safety Notes:Although wingstyle couplings are able to connect and disconnect while under pressure, it is recommended that hydraulic power supply be de-energized during connection to ensure operator safety. If it is not possible to de-energize the circuit, operators must be aware of their surroundings to ensure that an attachment or tool does not put them at risk, once hydraulic power is applied during the connection process.; W-series couplings are not recommended for continuous hydraulic impulse applications at rated pressures.; WARNING: Cancer and Reproductive Harm- http://www.P65Warnings.ca.gov Use:Not Available.
