Import American Types Hollow Adjustable Pipe Clamps For — Buy in Bulk from Supplier in China

Ningbo Six Rings Auto Parts Co., Ltd. manufactures American types hollow adjustable pipe clamps designed for securing pipes across plumbing, HVAC, and construction applications. These clamps feature a hollow band construction with an adjustable mechanism that accommodates variable pipe diameters without requiring multiple SKU sizes. The outer band edge receives a smoothing and shaping treatment to eliminate sharp edges that could abrade hose or pipe surfaces during tightening. The supplier notes industrial-grade material construction with corrosion resistance for indoor and outdoor service environments.

The American type designation refers to a clamp architecture with a perforated or slotted band that threads through a captive housing, allowing incremental adjustment via a screw mechanism, standard in North American and global industrial markets. Hollow band construction reduces weight while maintaining adequate clamping force for medium-duty applications. Typical material specifications for this clamp category include W1 (zinc-plated steel), W2 (stainless steel housing with zinc-plated band), W3 (all stainless steel), or W4 (AISI 316 stainless steel) grades per DIN 3016 classification, though the buyer should confirm the exact grade offered by this supplier. The smoothing treatment on the band outer edge is a critical quality step often omitted on economy clamps, as unsmoothed edges can cut into soft hose compounds under torque.

Primary applications include plumbing installations, HVAC ducting and refrigeration lines, automotive fluid routing, and general industrial maintenance. Buyers range from construction contractors and MRO distributors to OEMs integrating clamps into original equipment. The supplier indicates flexible minimum order quantities and offers FOB and CIF Incoterms with letter of credit or telegraphic transfer payment options. Given the zero percent response rate and harbor trust tier, buyers should initiate contact well in advance of critical deadlines and verify current production capacity and sample availability before placing volume commitments.

Ningbo Six Rings Auto Parts Co., Ltd. is located at No.225 Huangniyan Road, Mazhu Town, Yuyao District, Yuyao 315450, Zhejiang Province, China. The company operates as an imported supplier tier within the marketplace classification, indicating goods manufactured or sourced through cross-border supply chains rather than purely domestic Chinese distribution. The harbor trust tier represents a baseline verification level, and the supplier carries a zero percent response rate with zero average response hours recorded, which signals either a new listing, inactive account, or data collection gap that buyers should factor into communication planning.

The supplier's product focus centres on American types hollow adjustable pipe clamps for industrial and construction end markets. The listing describes smoothing and shaping treatments on band edges and industrial-grade corrosion-resistant materials as distinguishing features, though no factory size, year of establishment, employee count, revenue figures, or named clientele are stated. Buyers must independently verify production capacity, quality management certification status such as ISO 9001, and whether the supplier manufactures in-house or sources from sub-contractors. The Zhejiang location places the supplier within China's eastern manufacturing corridor with access to Ningbo-Zhoushan port for export shipments.
