End-cap fitting offering from Ouhao’s own product catalog.
The cap entry provides an end-closure fitting option within Ouhao’s pipeline range. Match the cap to the actual pipe bore, wall and service conditions. Supply the required material and dimensional reference, then confirm end preparation, cap geometry and inspection requirements for the selected fitting rather than assume a universal closure rating.
