We are Ningbo Welcome Pneumatic and Hydraulic Co., Ltd. based in Ningbo , China. We are member of companiess.com since September, 2010. Our business is related to Industrial Machinery industry and we specifically deal in Hydraulic Coupling. Please find our product details below:Flat Face Type Hydraulic Quick Coupling(Steel)LSQ-PT Features:1.Sleeve locking mechanism is engaged by rotating sleeve after connection. It prevents accidental disconnection when. The coupling is dragged along the ground. 2.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 incorporates a dust seal in the spring area. 3.Steel construction, zinc plated with yellow chromate finish. Hardened nipples and sleeves and solid barstock construction for maximum resistance to damage from hydraulic and mechanical shock. Anti-Blowout Nitrile/PTFE bonded seals is designed to prevent blow-out or damage during severe service conditions. 5.Durable ball-locking mechanism assures reliable connections, every time. A large number of locking balls distributes the 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.6.LSQ-PT Series 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 7.LSQ-PT series conforms to standard of ISO16028 with PARKER FE Series, FF Series, STUCCHIA8008 Series, AEROQUIP FD89 Series and HANSEN QA2900 Series. Performance:Test Fluid:Oil-200SUS, 1GPM=3.78L/Min, 1PSID=0.0069MPa.Thread Locked Type Hydraulic Quilk Coupling(Steel)KZE-B Features: from solid steel barstock for durability. KZE-B Series employs a threaded sleeve locking mechanism, mates with matching male threads on the nipple. The two halves must be manually threaded together for connection.3.Hard, chrome alloy balls are used for valving. They are spring loaded for positive seating of the valve. valve provides a metal-to-metal seal between the ball and coined seat. interface seal is polyurethane which resists high pressure extrusion.6.A threaded valve retainer provides a valve stop that assures positive valve alignment. with PARKER 3000 Series and FASTER PVVM Series.Performance:Test Fluid:Oil-200SUS, 1GPM=3.78L/Min, 1PSID=0.0069MPa.Thread Locked Type Hydraulic Quilk Coupling(Steel)KZE-B Features: from solid steel barstock for durability.
