Product Description ZJ-FF quick coupling features: ZJ-FF quick coupling series quick disconnect couplings are non-spill, push-to-connect quick disconnects designed for use in the construction and utility markets. The push-to-connect sleeve allows one handed connection and features a locking mechanism to prevent accidental disconnection. The flush face design eliminates hydraulic spillage and air inclusion when connecting and disconnecting. Anti-blowout seal on the male half prevents damage and premature failure with residual system pressure. Coupling bodies are steel with zinc and clear trivalent chromate plating (hexachromium free). AZJ-FF quick coupling series quick disconnect couplingsvailable in body sizes 1/4" through 1" with female pipe thread (NPSF), male pipe thread (NPTF), female straight thread (ORB), and female British Standard Pipe Parallel (BSPP) as standard end configurations. The ZJ-FF quick coupling series quick disconnect couplings 3/8" size conforms to HTMA (Hydraulic Tool Manufacturers Association) standards and both coupler and nipple are marked with a directional flow arrow. The ZJ-FF quick coupling series quick disconnect couplings' features: 1. New valve design, it cans resistance damage from high flow and the pressure of impulse that providing advanced performance. 2. Sleeve locking mechanism is engaged by rotating sleeve after connection. It prevents accidental disconnection when coupling is dragged along the ground. 3. Sleeve mechanism is designed to help prevent dirt from entering the internal mechanism and thus causing faulty operation when connecting or disconnecting. The sleeve covers the retaining ring and also 4. Incorporates a dust seal in the spring area. 5. Hardened nipples and sleeves and solid barstock construction make for a quality coupling with maximum resistance to damage from hydraulic and mechanical shock. 6. This Anti-Blowout Nitrile/PTFE bonded seal is designed to prevent blow-out or damage during severe service conditions. 7. Durable ball-locking mechanism assures reliable connection every time. A large number of locking balls distributes and work load evenly while providing alignment and swiveling action to reduce hose torque and prolong hose life. CAUTION: These products are not to be used as swivels; Rotation under pressure will result in excessive and premature wear. 8. ZJ-FF Series quick disconnect couplings employ flush valving when connecting or disconnecting. This means that the valves are mated together so that only small amounts of fluid can be lost during disconnection or air inclusion during reconnection. 9. New chrome plating treatment provides advanced anti-rust performance. 10. ZJ-FF quick coupling series conforms to the standard of ISO16028. Compatible with PARKER FE, FF Series, STUCCHI A8008 Series, AEROQUIP FD89 Series and HANSEN QA2900 Series. ZJ-FF quick coupling application: ZJ-FF quick coupling series quick disconnect coupling is widely applied for the public utility to avoid the leakage. Hydraulic oil leakage would cause a serious hazard, especially for the overhead bucket hoists when maintaining the high-voltage power lines. These couplings are also used for the hydraulic Tools's fast switchover in construction, railway maintenance and mining industries. Its easy cleaning function make it fit for the there special circumstances very well.
