0252900410 - ABA Original Hose Clamp 32-50mm Worm Drive Clip

Technical Overview: ESAB ABA Hose Clip 32-50mm

The ESAB 0252900410 is a premium-grade ABA Original hose clip designed for industrial applications requiring reliable, leak-free connections. Engineered with a clamping range of 32mm to 50mm, this component is essential for securing medium-diameter hoses in welding cooling systems, gas distribution manifolds, and general fluid transfer setups. The distinguishing feature of the ABA design is its non-perforated band. Unlike standard worm drive clamps that cut into the rubber or silicone of a hose through gear slots, the ABA band has a smooth interior profile with the gear teeth pressed into the band rather than cut through it. This design preserves the integrity of the hose material, preventing extrusion and damage even under high torque.

Structurally, the clip utilizes a one-piece pressed housing. This manufacturing technique eliminates the weakness associated with welded or riveted housings, ensuring that the screw remains perfectly aligned with the band threads during tightening. The result is a high clamping force that is distributed evenly around the circumference of the hose. The band edges are rolled upwards, a critical detail that prevents the sharp metal from cutting into the hose wall when the clamp is under tension or subjected to thermal expansion and contraction. This makes the clip particularly suitable for soft hoses used in liquid cooling units where temperature fluctuations are common.

Material composition typically involves high-grade carbon steel with a protective surface treatment (often AluZinc or similar corrosion-resistant coating) or stainless steel, ensuring longevity in industrial environments. The screw mechanism is designed for standard hex or flat-head drivers, allowing for easy installation and adjustment. In the context of ESAB's product line, this clip is often utilized for securing water return and supply lines on heavy-duty MIG and TIG welding power sources, as well as fume extraction ducting connections that fall within the 32-50mm diameter range. Its vibration resistance is a key specification, preventing loosening during the operation of heavy machinery.
