PP80-2-0801 - Polypropylene Schedule 80 Sr Threaded Fittings Brochure

PROGRESSIVE PRODUCTSFROM SPEARS ® INNOVATION & TECHNOLOGYVisit our web site: www.spearsmfg.comPOLYPROPYLENE SCHEDULE 80SR THREADED FITTINGS PP80-2-0801• Patented Special Reinforced (SR) Thread DesignSpears® patented Special Reinforced (SR) thread design is one of the most signi? cant advancements in the use of plastic threaded ? ttings. More than just an added metal 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. SR style ? ttings use type 316 Stainless Steel reinforcement.• Full 150 psi Pressure Rating For Threaded Systems Using SR Threaded FittingsSpears® SR threaded Schedule 80 Polypropylene ? ttings provide the reinforcement necessary to provide threaded systems with full 150 psi pressure rating for water @ 73°F, typically found only in fusion welded systems.• High Grade Homopolymer Compound - Excellent Chemical ResistanceSpears® selection of a premium polypropylene homopolymer provides improved purity with excellent chemical resistance to many solvents, caustic solutions and mixed chemicals for a wide variety of applications. Available in natural or black materials.• Wide Range of Threaded Con? gurations – IPS Sizes 1/2” Through 2”Spears® offers a wide assortment of Schedule 80 SR threaded Polypropylene ? ttings, including:90° Elbows Couplings Flanges Threaded Pipe Nipples45° Elbows Caps Blind FlangesTees Bushings Unions w/EPDM or Viton® Seals• Supplemental Line of Polypropylene Valves AvailableSpears® also offers a broad line of Polypropylene True Union Ball Valves, Diaphragm Valves and Butter? y Valves.Wide Selection of Confi gurationsHigh Grade Natural or BlackFeaturing Spears® SpecialReinforced (SR) Th readFull 150 psi Pressure Rating at 73°F180°F Maximum Service Temperature © Copyright 2008 Spears® Manufacturing Company.

PP80-2-0801SPEARS® MANUFACTURING COMPANYCORPORATE OFFICE15853 Olden St., Sylmar, CA 91342 • PO Box 9203, Sylmar, CA 91392(818) 364-1611 • www.spearsmfg.com Spears® Patented SR TechnologyBoosts Threaded Polypropylene Fitting PerformanceImproved Pressure Handling PerformanceDue to the highly ductile nature of Polypropylene, most threaded PP ? ttings are rated for system pressures of 25 psi @ 73° F. Pressure applications of up to 150 psi generally require more costly fusion weld jointing methods or use of a glass-? lled material which limits chemical resistance for some applications. Spears® Special Reinforced (SR) thread design boosts threaded PP ? tting performance by containment of expansion forces generated both during threaded joint make-up and higher system pressure operation. Laboratory test assemblies of Spears® Schedule 80 SR Polypropylene threaded ? ttings have been subjected to ASTM D 1598 sustained pressure test for 1000 hours at 320 psi without failure or loss of joint integrity.Sound PP Threaded ConnectionsSpears® recommends use of Spears® BLUE 75™ Thread Sealant for all SR threaded PP system connections to insure chemical compatibility and joint integrity. Tape type thread sealant can cause unwanted wedging action between threads. Choice of an appropriate thread sealant is at the discretion and responsibility of the installer. Spears® Schedule 80 SR Polypropylene ? ttings are assembled with an adhesive to position the reinforcing ring. If ring is loose, simply check that it is seated against the face of the ? tting when assembling joint. A loose or spinning ring does not reduce its function upon installation. 1 to 2 turns beyond ? nger tight are generally suf? cient to make a sound joint. Unnecessary over tightening can result in stripping of threads or other pipe and ? tting damage.NOT FOR USE WITH COMPRESSED AIR OR GASESNo warranty of service is implied or expressed on the basis of this literature by Spears® Manufacturing Company, Sylmar, California.
