The LD-347 galvanized steel cushioned pipe clamp and riser clamp assortment provides plumbing, HVAC, and mechanical contractors with a complete range of rubber-lined pipe supports designed to hold pipes firmly while isolating them from the structure that carries them. Each clamp is formed from a galvanized steel band that wraps around the pipe and closes with a zinc-plated bolt and nut, while an integral EPDM or neoprene rubber cushion lining sits between the steel and the pipe surface. This cushion performs two critical functions: it grips the pipe without scratching or deforming thin-walled copper, PEX, or plastic tubing, and it dampens vibration and structure-borne noise that would otherwise travel from pumps, compressors, and flowing water into the building frame.

The assortment covers nine standard pipe diameters from 1/2" (15mm) up to 4" (100mm), encompassing the full range of common residential and light-commercial service piping. Band widths from 15mm to 25mm and steel thicknesses from 1.5mm to 2.5mm scale with pipe size, so larger-diameter risers receive the wider, stiffer band needed to carry the combined weight of pipe, fluid, and fittings without sagging over long vertical runs. The rubber lining also accommodates thermal expansion and contraction, allowing the pipe to move slightly as it heats and cools without transmitting stress to the support point or losing its grip on the pipe.

Coating options include the standard silver/galvanized finish for general indoor and covered outdoor corrosion resistance, a black coating for industrial and mechanical-room applications where a low-visibility appearance is preferred, and a green coating that aligns with color-coded piping conventions in many building standards. The zinc-plated bolt and nut resist seizing and corrosion, ensuring that clamps can be adjusted or removed during maintenance without the fastener snapping or galling.

For wholesale buyers, the LD-347 supports full OEM customization including custom pipe diameter ranges, band width and steel thickness, rubber lining material, coating color, logo printing, and tailored assortment compositions for specific project requirements. With an MOQ of 500 pieces, mixed-order flexibility, and CE / ISO 9001 / RoHS / SGS compliance, it is an ideal stock item for plumbing wholesalers, HVAC distributors, and building-services fastener importers.
