Product Spotlight | Welping Stub End Holders: Adjustable Clamping for HDPE Stub End Fusion

Oct 10,2026

Welping HDPE stub end holders secure stub ends for butt fusion welding with a compatible fusion machine. Featuring a steel plate structure, adjustable clamping blocks and hand knobs, they allow operators to adjust both clamping position and tightness. Multiple models and custom sizes are available.
Adjustable Clamping Design

The clamping blocks slide along slots in the plate. By loosening the fixing bolts, operators can reposition the blocks to suit the stub end dimensions, then tighten the bolts to lock them in place.

The black hand knobs adjust clamping tightness to secure the stub end. Together, these adjustments help operators set up the holder for different stub end sizes within each model’s clamping range.
Product Demonstration
The video below shows the holder’s structure, sliding clamping blocks and hand knob adjustment.

Welping offers stub end holder models from 160 to 2250. The images below feature the 160, 200, 250 and 315 models. Please contact us for additional models and sizes.
Model designations do not indicate the full clamping range. The actual clamping range and mounting compatibility should be confirmed for the selected model, fusion machine and stub end dimensions.
Machine Compatibility and Customization
Mounted on a compatible butt fusion machine, the holder secures the stub end for alignment with the pipe and subsequent welding operations.
Custom sizes and mounting configurations are available for specific requirements. To help us recommend a suitable holder, please provide your fusion machine brand and model, stub end dimensions, and photos of the mounting area.
