Product Specs:

• For MLS 3/4" AND 1" vented loop
• Includes cap and duckbill (rubber grommet)
• The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. The duckbill one-way valve is designed to seal properly if particulate matter is present in fluids.
