Import Best Cost Performance Quick Camlock Couplings — Buy in wholesale FOB from Supplier in China

Jinan Double Well International Trade Co., Ltd. supplies brass quick camlock couplings in sizes from 1/2 inch to 6 inch, with thread options in NPT, BSPP, and BSPT. The couplings are manufactured by gravity casting or die casting in brass, with pins, rings, and safety clips available in carbon steel plated or stainless steel. Handles material options are brass or stainless steel. Sealing is provided by NBR, BUNA, EPDM, or VITON elastomers, giving a working temperature range from -101°C to +232°C (150°F to +450°F) and a maximum working pressure of 250 psi. The product conforms to A-A-59326 (formerly MIL-C-27487) or DIN 2828 / DIN 14420-7 standards.

The abrasion-resistant, no-sparking brass construction offers a cost advantage over stainless steel alternatives for low-pressure suction and discharge applications. Typical uses include oils, coolants, and water transfer in pump, tank, IBC, and paint and ink industry settings. The cam and groove mechanism allows tool-free connection and disconnection, with the locking arms secured by a safety clip. The supplier explicitly notes these couplings are not suitable for steam, compressed air, or liquid gas applications, a critical limitation for buyers in process industries. Gravity and die casting are both employed, gravity casting typically yielding slightly better material integrity for thicker sections, while die casting offers tighter dimensional control and faster production.

Buyers for fluid-handling distributors, agricultural equipment makers, and industrial maintenance suppliers form the core market. The couplings suit hose assemblies where frequent changeover is needed and spark resistance is valued. Importers should confirm with Jinan Double Well the exact alloy specification of the brass bodyWM (CW617N, CZ132, or equivalent), request material certification, and verify whether the quoted temperature range applies to all seal options or specifically to VITON. Packaging is polybag inner, carton outer, with FOB Qingdao as the stated delivery basis. Lead time, exact MOQ, and payment terms beyond 30 percent deposit require direct confirmation.

Jinan Double Well International Trade Co., Ltd. is located at Dangyang Road 3166 in Huaiyin Zone, Jinan, Shandong Province, China, postal code 25000. The company holds a harbor trust tier on the platform with a 0.00 percent response rate and zero recorded average response hours, indicating minimal or no active engagement through this channel at present. The supplier operates from Jinan, a city with established metalworking and machinery manufacturing clusters, though this does not in itself confirm in-house casting capability.

The listing presents Jinan Double Well as trading in camlock couplings, Storz couplings, Bauer Guillenmin couplings, stainless steel pipe fittings, valves, flanges, sanitary fittings, and related products. No information is provided about factory ownership, ISO certification, export licence, years in operation, workforce size, or annual turnover. Buyers should verify directly whether the company manufactures castings in Shandong or sources from subcontracted foundries, and whether they maintain inventory or operate on make-to-order for the full size range.
