Key benefits and what this product solves Dual inner sizes (32/35MM): accepts either 32 mm or 35 mm connections so you can use one connector with most vacuum hoses and attachments. Eliminates the need to multiple adapters and avoids mismatched fittings. Universal use: designed for both household cleaning and industry dust collection tasks, giving a single solution for home vacuums and vacuums. Threaded structure for a tight seal: the threaded connection prevents air leakage and minimizes suction loss, maintaining consistent performance while in use. Soft bellows tube for flexibility and access: the bellowsstyle tube bends easily to reach narrow or awkward spaces, compresses for compact storage, and adapts to movement without detaching. Key attributes Function: secure hose/attachment connector that maintains suction and prevents leaks. Compatibility: inner diameters 32/35MM — fits the majority of standard vacuum cleaner and dustcollection hoses and attachments. Size: dual inner sizes specified as 32/35MM to match common hose standards. Material/style: soft bellows tube for flexibility and easy handling. Performance: threaded coupling ensures a stable, airtight connection during operation. Practical applications (use scenarios) Home cleaning: connect to your vacuum for cleaning stairs, narrow couch crevices, behind radiators, or car interiors where flexible bending and a secure fit are required. Workshop dust collection: attach to a vacuum or dust extractor for pointofuse extraction on sanders, routers, or table saws where a tight threaded connection prevents loss of suction. Professional maintenance: use in routine building or facility cleaning where varying hose diameters and tight seals are needed to keep suction consistent across tasks. Why customers choose this product Solves compatibility problems by supporting two common inner diameters (32/35MM). Prevents suction loss with a threaded, airtight connection. Provides practical flexibility and storage convenience with a soft bellows design. Suitable for both household and industrial dust collection tasks, reducing the need for multiple specialized parts.
