- 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.
- Stainless steel reinforced adapters give extra strength to threaded joints used where pipe dismantling takes place for occasional cleaning or modification.
- PVC is not recommended for use with chlorinated or aromatic hydrocarbons, esters, or polar solvents such as ketones.
- Spears® PVC materials conform to ASTM Cell Classification 12454 (formerly designated as Type I, Grade 1). The maximum recommended service temperature of PVC products is 140° F (60° C).
- PVC has excellent chemical and corrosion resistance to a broad range of fluids including water, deionized water, most mineral acids, alkaloids, salts, and paraffinic hydrocarbon solutions.
