Couplings create straight inline connections between pipe segments, while keeping full transparency across joints.
Equipped with an internal centre‑stop to guarantee equal pipe insertion depth, these connectors support continuous inline visual inspection of fluid media. Suitable for connecting sight‑glass pipelines for chemical processing, water purification and experimental‑filtration systems.
Straight Inline Visibility: Maintains continuous visual inspection across jointed pipe sections for seamless flow monitoring.
Integrated Pipe Stop: Features an internal center stop to guide precise pipe insertion and balance structural joint strength.
High Chemical Inertness: Resists acids, bases, and aqueous solutions without discoloration or material degradation.
Easy Installation: Precision socket tolerances allow fast, leak-proof bonding using standard PVC solvent cements.
