Product Description
The LEGEND VALVE 313-414 is a 3/4-inch IPS stainless steel insert stiffener designed to reinforce flexible tubing connections in underground water service applications. The stiffener inserts into the end of plastic or soft tubing to prevent collapse when a compression or grip-style fitting is tightened down. Constructed from stainless steel for corrosion resistance, this part conforms to AWWA C 800, the standard covering underground service line materials. It weighs 0.06 pounds and measures 0.9 x 2.5 x 0.9 inches. Plumbers and water service technicians install this component as standard practice wherever IPS-sized tubing is joined at a service fitting.
This insert stiffener is used in residential and light commercial water service installations, typically at meter setters, curb stops, and other underground or in-wall connection points where flexible IPS-sized tubing meets a compression-style fitting. It is appropriate for use in potable water service lines where tubing wall integrity must be maintained under fitting compression loads. The 3/4-inch IPS size is among the most common in residential water service work.
Key Features
- Stainless steel construction resists corrosion in wet and underground environments
- Conforms to AWWA C 800 for underground service line applications
- 3/4-inch IPS sizing fits the most common residential water service tubing diameter
- Prevents tubing wall collapse under compression fitting load
- Compact form factor at 0.9 x 2.5 x 0.9 inches and 0.06 pounds per piece
Compatibility
Designed as an OEM-style insert stiffener for use with 3/4-inch IPS flexible tubing in compression and grip-style water service fittings. Compatible with systems conforming to AWWA C 800 requirements.
Installation Notes
Installation is typically performed by licensed plumbers during water service line work. Shut off the water supply and relieve line pressure before cutting tubing or disassembling fittings. Insert the stiffener fully into the tubing end before seating the tubing into the compression fitting body. Verify the stiffener is fully seated and that the tubing end is square-cut before tightening the compression nut.
