Spears - Model ESR-2-0805 -PVC & CPVC Encapsulated Special Reinforced Fittings
Spears patented SR technology is now available in a new PVC & CPVC Encapsulated SR design. Specii cally produced for use in harsh ambient chemical environments where exposed stainless steel cannot be tolerated. h e external reinforcing ring of Spears regular SR Female Adapter is fully encapsulated in PVC or CPVC plastic for maximum chemical resistance. Available in IPS sizes 1/4” through 2”.
Patented Advanced Design
Spears Patented Schedule 80 Special Reinforced (SR) Fittings reduce problems associated with over tightening of female plastic pipe threads. Not just an added ring, this unique precompression design compensates for expansion forces generated from tapered pipe thread joint make-up. Radial-stress is reduced in normal installations and contained in severe over tightening situations.
Excellent Plastic-to-Metal Transition
Fitting - Without Pressure De-Rating
Spears patented SR design and manufacturing process allows direct connection to threaded metal pipe through one simple adapter. Superior Strength of the SR Fitting eliminates the need for pressure de-ratings in system transitions normally associated with traditional non-reinforced plastic threaded fittings. Material thermal expansion/contraction differences are equalized by the restraining collar. You get low cost, worry-free plastic-to-metal transitions every time.
