Use .820 Coupling with drip irrigation tubing to connect 3/4" drip poly tubing (.820" OD), and or .820 soaker hose. Also good for repairs that goof plugs can't handle. Cut out the damaged section of poly tubing and repair with a coupling on either side of the piece you cut out. Compression fittings require no glue. Compression end (black ring stamped 800) accepts .820-.830 OD drip tubing, soaker hose.
