Polypropylene Type D Camlock Coupling (Female Coupler × Female Thread)

Product Specification

Feature

JINGYE Fittings manufactures Polypropylene Type D Camlock Couplings for quick connection between compatible male cam-and-groove adapters and male-threaded fluid-handling equipment. Each PP female coupler features an integral female pipe thread, dual cam arms and a replaceable internal gasket. Key Product Advantages: 1. Nine Nominal Sizes and Unified Model Identification The 1/2"–4" series comprises JY-050-D-PP, JY-075-D-PP, JY-100-D-PP, JY-125-D-PP, JY-150-D-PP, JY-200-D-PP, JY-250-D-PP, JY-300-D-PP and JY-400-D-PP, including 2-1/2" (DN65). Consistent model codes simplify technical sourcing, distributor inventory and mixed-SKU purchasing. 2. Lightweight PP and Reinforced PP Options Polypropylene (PP) construction reduces component weight and offers resistance to many chemically compatible acids, alkalis and aqueous fluids. Glass-fiber-reinforced polypropylene (GFPP) options provide enhanced rigidity and dimensional stability for suitable designs. Material suitability depends on chemical concentration, temperature and exposure time. 3. Female Camlock x Female Pipe Thread Design Type D combines a female cam-and-groove socket with an internally threaded pipe connection. The coupler attaches to a compatible male-threaded valve, pump, tank or pipe fitting. Unlike Type B, both the camlock socket and pipe-thread connection are female; unlike Type C, no hose shank is incorporated. 4. BSPP, BSPT and NPT Thread Selection Female-thread configurations may include BSPP (G, ISO 228-1), BSPT (Rc, ISO 7-1) and NPT (ASME B1.20.1). Thread diameter, pitch, engagement depth and alignment are controlled for connection fit. The selected sealing method must match the thread form, while assembly torque must account for polymer deformation, creep and possible stress cracking. 5. Compatible with Type A, Type E and Type F The Type D female socket connects with dimensionally compatible Type A, E and F male camlock adapters. Cam-and-groove profiles may follow A-A-59326 (formerly MIL-C-27487) and applicable EN 14420-7 / DIN 2828 interface designs. Matching socket geometry and adapter dimensions are essential for proper engagement. 6. Dual Cam-Arm Quick Locking Two pivoting cam levers engage the annular groove on a male adapter and compress its face against the coupler gasket. Corrosion-resistant stainless steel lever and pivot hardware options support repeated assembly and disassembly. Controlled arm travel, pin retention and socket dimensions promote reliable mating operation. 7. Replaceable Gaskets for Fluid Compatibility The female camlock socket accommodates a replaceable sealing gasket. Available gasket selections include NBR (Buna-N), EPDM, FKM and silicone, depending on fluid compatibility and temperature. The camlock face gasket and the separate female-thread sealing interface must both suit the application. 8. Precision Injection Molding and Dimensional Control Injection molding forms the female socket, threaded bore, gasket seat, cam-arm mounting points and flow passage. Resin processing, mold design, cooling and shrinkage control support consistent geometry. Clean molding surfaces, trimmed gates, removed flash and unobstructed flow bores improve assembly quality. 9. Quality Inspection and Functional Verification JINGYE Fittings operates under ISO 9001:2015 quality management. Checks cover resin identity, molding condition, female-thread dimensions, socket depth, gasket seating, cam-arm movement, pivot retention and visual finish. Matched-adapter connection, thread fit, repeated operation and agreed leakage tests support application-specific verification. 10. OEM Customization and Flexible Supply Customization options include PP/GFPP formulations, BSPP/BSPT/NPT thread variants, gasket materials, cam hardware, molded colors, product identification and private-label packaging. JINGYE Fittings supports samples, tooling development, drawings, mixed-size orders, repeat production and alternative sourcing. 11. Chemical Processing, Water Treatment and MRO Use Type D supports compatible chemical-transfer equipment, water and wastewater treatment, chemical dosing, agricultural spraying, fertilizer handling, irrigation, IBC transfer and industrial maintenance. Female-threaded PP camlock couplers provide a lightweight quick-connect interface for suitably rated pumps, valves, tanks and piping systems.
