Aluminum Camlock Dust Plug (Type DP – Male Dust Plug for Female Camlock Couplers)

Product Specification

Feature

JINGYE Fittings manufactures Aluminum Camlock Dust Plugs (Type DP) for protecting disconnected female cam-and-groove couplers. The closed-end male plug helps keep dust, dirt and debris away from coupling sockets and gasket-contact surfaces during storage, transport and maintenance. Key Product Advantages: 1. Twelve Sizes and Consistent JINGYE Model Codes Available in 1/2"–8": JY-050-DP-AL, JY-075-DP-AL, JY-100-DP-AL, JY-125-DP-AL, JY-150-DP-AL, JY-200-DP-AL, JY-250-DP-AL, JY-300-DP-AL, JY-400-DP-AL, JY-500-DP-AL, JY-600-DP-AL and JY-800-DP-AL. The unified model series simplifies replacement sourcing, distributor inventories and mixed-size accessory orders. 2. Closed-End Male Dust Plug Design Type DP features a male camlock nose, annular locking groove, sealing-contact face and closed end. Unlike flow-through Type A, E and F adapters, the DP plug has no through-bore, pipe thread or hose shank. It is intended to close and protect an unused female camlock opening. 3. Female Coupler Compatibility The male plug fits compatible Type B, Type C and Type D female camlock couplers. The interface geometry references applicable A-A-59326 (formerly MIL-C-27487) and EN 14420-7 / DIN 2828 configurations. Matching nose diameter, insertion length, groove location and gasket-contact geometry supports proper engagement. 4. Secure Cam-Arm Retention The female coupler's cam levers engage the DP plug's annular groove and hold it in place during idle periods. This uses the existing camlock locking mechanism without separate threaded fastening. Accurate groove width, depth and nose geometry support repeatable insertion and removal. 5. Protection Against Dust and Contamination A closed plug covers the coupler mouth during hose changes, equipment storage, transportation and planned shutdowns. It helps prevent dirt, sand, dust and foreign particles from contacting the internal gasket and socket. Clean mating surfaces reduce cleaning work before the next hose connection. 6. Gasket Contact and Protective Closure The DP sealing face contacts the gasket already installed in the female coupler. Common gasket options include NBR (Buna-N), EPDM, FKM and silicone, selected to match the coupler and operating environment. The dust plug is a protective closure for disconnected equipment, rather than a substitute for a pressure-rated end closure. 7. Lightweight Aluminum and CNC Accuracy Cast aluminum alloy provides convenient handling, particularly for larger nominal sizes. Precision CNC machining controls male nose dimensions, locking groove profile, sealing-contact face and fit-related features. Natural aluminum is the standard finish; optional markings and selected surface treatments support OEM identification. 8. Optional Retaining Chains and Handles Retaining chains, pull rings or handling features can be configured for easier plug management. Tethering a dust plug to the corresponding hose or equipment connection reduces the chance of misplacement during repeated maintenance. Accessory choices can be aligned with site handling practices. 9. Quality Inspection and Functional Fit JINGYE Fittings follows an ISO 9001:2015 quality management system. Inspection focuses on casting condition, nose diameter, groove width and depth, sealing-face finish, burr removal and visual consistency. Functional checks can include mating fit, cam-lever engagement, secure retention and gasket-contact verification. 10. OEM Customization and Flexible Purchasing Options include plug dimensions, attachment features, cast or laser markings, private labeling, finish and packaging. JINGYE Fittings supports drawing-based development, physical samples, mixed-SKU orders, distributor replenishment, bulk purchasing and repeat production for industrial camlock accessory programs. 11. Industrial Applications and Second-Source Support Type DP plugs serve industrial hose assembly shops, irrigation systems, tanker loading equipment, fuel and chemical transfer facilities, construction dewatering, mining operations and plant MRO. Buyers may submit mating couplers, drawings, samples or existing item references for dimensional matching and alternative-source procurement.
