Description
The Mazco Safe-T-Stopper is an engineered and patented stopping tool that enables safe, gas-free service tee abandonment or renewal on natural gas distribution systems. It mounts over the service tee and creates a sealed working environment by attaching a ball valve and using specialized adapters to remove the cap or plug, then stopping the gas with a rubber or self-tapping plug. This approach lets technicians isolate and cut or replace tees without releasing gas into the atmosphere, improving worker safety and reducing environmental impact.
Designed in response to industry safety standards and regulatory changes, the Safe-T-Stopper works on a wide range of tees that lack internal stopping mechanisms, helping utilities and contractors avoid costly line-stop procedures while enhancing productivity and lowering restoration costs.
Pressure ratings and configurations vary with tee type and procedure, and Mazco offers a comprehensive range of adapters and parts to fit different applications.

Value Elements
- Gas-Free Service Tee Isolation
- The Mazco Safe-T-Stopper allows crews to isolate service tees without releasing natural gas, helping improve jobsite safety and reduce emissions.
- Avoids Unnecessary Line Shutdowns
- The tool helps utilities complete service tee work without shutting down larger sections of the system, reducing customer disruption and simplifying field work.
- Improved Public and Operator Safety
- By creating a sealed working environment around the tee, the Safe-T-Stopper helps keep gas contained while crews complete the work.
- Adaptable to Multiple Tee Types
- The Safe-T-Stopper can be used on different service tee configurations, including open-gut, pipe tees, street tees, and NO-BLO service tees.
Comparison vs. Next Best Alternative
- No Natural Gas Release
- Compared with traditional service tee work that may involve blowing gas or more invasive shutdown procedures, the Safe-T-Stopper keeps the work gas-free.
- Less Disruption Than Line Shutdowns
- Instead of shutting down service or isolating larger sections of pipe, crews can complete the work directly at the tee.
- More Flexible in the Field
- Its adapter-based system allows it to work across many service tee styles, making it more versatile than single-purpose stopping tools.
- Parts and Accessories Available
- Supporting parts and accessories are available and ready to ship, helping crews keep the tool system service-ready.
Where Do I Use This Product and Why?
- Service Tee Isolation
- Use the Safe-T-Stopper to isolate gas tees when they need to be cut, replaced, plugged, or abandoned.
- Service Tee Renewal or Abandonment
- The tool allows crews to stop the gas at the tee so the service connection can be renewed or abandoned according to utility procedures.
- Natural Gas Distribution Service Work
- Ideal for gas utility crews working on live service lines where safety, speed, and minimizing gas release are priorities.
- Applications Where Shutdowns Should Be Avoided
- Use it when a larger line shutdown would add time, cost, or customer disruption.
