Spears® EverTUFF® TURF™ Swing Joint Riser Assemblies are precision engineered for use in turf and landscape irrigation applications. Molded to a strong Schedule 80+ design from high quality PVC, Spears® Swing Joint Riser Assemblies offer full 360° adjustment on three planes.
Heavy Schedule 80+ Design
Computer engineered for optimum performance, Schedule 80+ design is substantially heavier than other PVC swing joints manufactured to Schedule 40 or Class 200 specifi cations. Spears® design places additional material in critical areas to reduce typical stress concentration and guard against stress cracking.
Strong Buttress Threads
Buttress threads provides superior strength in high stress, omni-directional pressure applications, such as that encountered with pressure surges. Longer thread design allows free movement of the joint without restriction.
Double O-ring Seals
Pre-lubricated double O-ring seal at Buttress threaded joints provides both positive, leak-free sealing and protection from joint damage due to entry of sand, dirt and debris.
Sweep Style Fittings
Full bore, Schedule 80+ medium sweep design optimizes flow and reduces friction loss over conventional block or square elbow patterns. Larger finger knurls eliminate need for wrenches or other tools during installation or adjustment.
Pressure Rated and Fully Tested
Spears® swing joints have a maximum internal pressure rating of 315 psi at 73°F and fully tested for the most demanding applications through ASTM D 1599 hydrostatic burst tests, ASTM D 1598 sustained pressure tests, ASTM D 3139 Class 315 leak tests, and Spears® own cyclic pressure testing program.
