T-joint for irrigation riser pipes includes sockets and riser locked to T-joint

摘要

A connection for a high pressure fluid supply system includes an inverted T-junction member and a riser 7. The inverted T-junction member has standard socket ends 2 & 3 on its cross-member and a lockable socket end 6 on its upwardly extending leg. Lockable socket end 6 has at least an opposed pair of radially extending holes 11 & 12. Riser 7 has a complementary set of holes 14 & 15. The arrangement is such that in use with a sealing ring between riser 7 and lockable socket end 6 inserted in the upwardly extending leg, a locking means is sealingly inserted in each of the radially extending holes to be engaged in the holes in riser 7 to lock and locate the inverted T-junction with the riser 7.
