Loose pipes, vibrating cables, and leaking gas lines are a DIYer's nightmare. Whether you're running plumbing under a sink, routing conduit in a workshop, or securing irrigation lines outdoors, you need a clamp that holds firm and won't corrode. These 304 stainless steel U-bolt hose clamps are built for homeowners, tradespeople, and industrial maintenance crews who demand reliability.
Each clamp is precision-formed from AISI 304 stainless steel with a natural brushed finish (Ra ≤ 1.2μm). Available in 18 inner diameter sizes ranging from 10mm (≈3/8") to 115mm (≈4-1/2"), with M4 threaded hardware and a torque strength of ≥25N·m. Rounded edges and a fully enclosed structure prevent pipe damage during installation.
Use them to fasten water supply pipes in bathrooms and kitchens, bundle electrical conduit or cable trays in workshops, secure gas lines in HVAC installations, or mount irrigation tubing in garden and agricultural setups — anywhere a dependable, corrosion-resistant clamp is needed.
Securing water supply lines, drain pipes, or shower hoses under sinks and behind walls — where a rust-free, long-lasting clamp matters most.
Bundling conduit, cable trays, or pneumatic lines in factories and workshops where vibration and temperature swings demand a clamp rated for -50°C to +300°C.
Mounting PVC or rubber irrigation tubing outdoors, where UV exposure and moisture make stainless steel the only sensible choice over zinc or plastic clamps.
Fastening gas supply pipes and HVAC refrigerant lines where torque requirements (≥25N·m) and temperature resistance are non-negotiable for safety compliance.

The 5-Piece Set is a complete kit that typically includes the U-bolt clamp body along with matching nuts and washers as a ready-to-install assembly. The 5-pcs option provides 5 individual clamp units. Both include stainless steel M4 hardware — select the variant option above to confirm what's included for your chosen size.
These clamps are manufactured from AISI 304 stainless steel and have passed a 2000-hour salt spray corrosion test. They are suitable for outdoor, marine-adjacent, and high-humidity environments. For highly aggressive saltwater or chemical environments, 316 stainless steel may be preferable.
These clamps are compatible with any round pipe, hose, or conduit within the listed inner diameter range, including PVC, copper, galvanized steel, rubber hose, and electrical conduit. The rounded edges protect softer materials like rubber and plastic from abrasion.
Select the inner diameter that matches the outer diameter of your pipe or hose. For example, if your pipe has a 25mm outer diameter, choose the M25 variant. If you're between sizes, generally size up to ensure the clamp can be tightened securely without over-stressing the pipe.
These clamps are rated for a torque strength of ≥25N·m. For most residential plumbing and cable management applications, tightening to hand-tight plus a quarter turn is sufficient. Always follow the torque requirements specified by your pipe manufacturer or installation standard.
These 304 stainless steel U-bolt clamps are commonly used to secure gas supply pipes in HVAC and plumbing installations. However, always verify that your specific installation complies with local building codes and gas safety regulations. Consult a licensed professional for gas line work where required by law.
Yes. The operating temperature range is -50°C to +300°C (-58°F to +572°F), making them suitable for hot water pipes, steam lines (within the rated range), and industrial environments with significant temperature variation.
