Hot tap and Line Stop fitting

Description

Hot Tapping and Line Stop Fittings are specially engineered components designed to provide safe, leak-proof connections on live pipelines during hot tapping and line stopping operations.

These fittings enable branch connections, valve installations, and pressure testing without the need to interrupt or depressurize the flow of oil, gas, water, or process fluids.

They are widely used across Oil & Gas, Refinery, Petrochemical, Power, and Industrial pipeline systems, ensuring operational safety, reliability, and efficiency.
