Flat head hydraulic quick connector (carbon steel)

●

HJ-PT connectors are widely used in the following utilities: Hydraulic oil leakage can pose a serious safety hazard, especially for overhead bucket cranes used for high-voltage power transmission line maintenance. This type of connector is also used for rapid switching of hydraulic machines in construction, railway maintenance and mining, and its easy cleaning makes it ideal for use in such special environments.

●

The sleeve locking mechanism is engaged by rotating the sleeve after connection and prevents accidental disconnection when the connector is dragged along the ground during use.

●

The design of the sleeve locking mechanism helps prevent debris from entering the internal mechanism and causing erroneous operation when connecting or disconnecting. The sleeve covers the retaining ring and contains a dust seal in the spring area.

Durable ball-lock mechanism ensures a secure connection every time. Several locking steel balls evenly distribute the workload. Provides both alignment and rotational action to reduce hose twist and extend hose life. WARNING: These products are not intended for use as swivel nipples. Rotation under pressure will cause excessive and premature wear.

HJ-PT series fittings operate with a flush valve mechanism when connecting and disconnecting. This means that the joint between the valves allows only a small amount of fluid to be lost when disconnecting, or only a small amount of air to be mixed when reconnecting.
