The L12-TL incorporates a large working surface, larger cover and a gauging and sampling hook into the base. The base is inclined to match the slope of the API 12 tank’s roof to provide a level working surface.
The L12-TL outperforms the competition with industry-leading flow rates and high-precision tolerances for a superior seal. A leakage rate less than 1 SCFH of air at 90% of set pressure keeps your tanks in compliance with industry standards.
Thief hatches are used on steel or fiberglass (FRP) low-pressure oil tanks to provide access for level gauging, sampling and overpressure or vacuum protection, all in one compact design.

Round Pan Thief Hatch
The L12-TH Thief Hatch outperforms the competition with industry-leading flow rates and precision tolerances to provide a superior sealing performance. Leakage rates less than 1 SCFH at 90% of set pressure keeps your tanks industry-standard compliant. A bonding strap and SLIC™ pins come standard with the L12-TH.View Round Pan Thief Hatch chevron_right
Use the L1220A to pipe away vapors in pressure and vacuum relief systems. The L1220A routes vapors through a flanged outlet connection, providing increased fire protection and safety.View Pipe-Away chevron_right
Pressure Relief Valve
The L2300A provides emergency relief capacity above what can be supplied by standard operating valves. Use it to protect tanks, piping and low-pressure vessels from internal pressure damage.View Pressure Relief Valve chevron_right
Vent to Atmosphere
Model L1200A protects your tanks from damage created by overpressure or excessive vacuum. It reduces costly product evaporation losses due to normal tank “breathing.” It also minimizes atmospheric contamination by retaining toxic vapors, providing increased fire protection and safety.View Vent to Atmosphere chevron_right
