Unions adopt a 3-piece structure with threaded collar and EPDM / Viton O-ring seals for easy maintenance and fast system disassembly. The transparent body lets operators check fluid quality and internal seal status in real time. Sections can be removed for cleaning or part replacement without cutting the pipeline.
Quick Disconnect Mechanism: Threaded collar allows fast line separation for routine maintenance, cleaning, or equipment replacement.
Visual Seal Monitoring: Clear union body enables instant visual inspection of internal O-ring seating and fluid passage.
Leak-Free Union Seal: High-quality elastomeric O-ring guarantees a tight, pressure-resistant seal under repeated assembly.
Durable Solvent Hubs: Socket ends bond securely with clear PVC pipes to maintain overall system pressure ratings.
