Junjin Spare Parts Clamp 5" Metric 1 Bolt RB50001

This is a genuine 5-inch metric 1-bolt clamp, part number RB50001, engineered as a direct-fit replacement for Junjin concrete pump systems. It secures 5” (DN125) pipeline connections, ensuring tight, leak-free joints under high-pressure concrete flow. Built to original equipment specs, it matches the fit and performance of the factory part.

Constructed from high-grade forged steel, this clamp delivers exceptional strength and wear resistance on job sites. Its robust one-piece forging resists deformation, while a corrosion-resistant finish stands up to moisture, concrete slurry, and harsh weather. The single metric bolt design balances durability with easy maintenance.

Designed for fast, tool-friendly installation, the 1-bolt mechanism simplifies assembly and disassembly. The precision-machined inner ring aligns perfectly with 5” pipe flanges, and the heavy-duty bolt tightens securely to maintain clamping force during vibration and pressure spikes. No specialized tools are needed for routine service.

Ideal for Junjin boom pumps and line pumps, this clamp handles the rigors of continuous concrete transfer. It reliably connects pipes, elbows, and hoses in high-pressure circuits, preventing costly leaks and downtime. The metric sizing ensures compatibility with standard DN125 concrete pump components.

As a trusted Junjin spare part, RB50001 undergoes strict quality checks for consistent performance. It meets industry standards for concrete pump fittings, offering a cost-effective, long-lasting solution for repair and maintenance. This clamp keeps your Junjin equipment running efficiently on every job.
