Fuseal Fast-Lock Long Turn Tee Wye 91.2° Reducing (S x S x S)

  Datasheet (PDF)

The Georg Fischer Fuseal Fast-Lock Long Turn Tee Wye 91.2° Reducing (S x S x S) is an engineered polypropylene mechanical joint fitting designed for corrosive chemical waste and drainage systems. Configured with a smooth 91.2-degree sweep and reducing branch sockets, it provides directional flow transition between horizontal and vertical drain lines in laboratory, pharmaceutical, and industrial installations requiring rapid assembly and chemical resistance.

Technical specifications

The Fuseal Fast-Lock reducing long turn tee wye provides a sweep branch transition for directional drainage with integrated mechanical joint connections. It is engineered for corrosive waste drainage with intermittent pressure and vacuum capability.

• Component configuration: Reducing long turn tee wye at 91.2 degrees (sweep pattern)
• Connection type: Socket x socket x socket (S x S x S) mechanical joint
• System operating pressure: Rated for 35 psi for vacuum and pumped drainage
• Continuous service temperature: Up to 180 degrees F (82 degrees C)
• Intermittent discharge temperature: Up to 212 degrees F (100 degrees C)
• Tool requirement: Standard 8 mm or 10 mm socket driver with no grooving required

Materials and standards

Manufactured from flame-retardant polypropylene (PPFR), this fitting provides dependable resistance against aggressive acids, alkalis, alcohols, solvents, and salt solutions. Dilute mineral acids and aqueous acid salt solutions have no corrosive effect on the material structure.

The material will not rust, pit, scale, or corrode, and it is unaffected by electrolysis. It resists degradation from chemical exposure, with vulnerability limited to strong oxidizing acids, select organic solvents, and chlorinated hydrocarbons. For above-ground installations, the pigmentation protects the fitting against solar ultraviolet radiation and is heat-stabilized for handling hot chemical reagents. The fitting is fully compatible with Schedule 40 and Schedule 80 flame-retardant (PPFR) as well as non-flame-retardant (PPNFR) polypropylene piping.

Installation and jointing

The Fast-Lock mechanical joint mechanism delivers rapid, dry jointing without solvent cement, open flames, or hazardous fumes. Joints require no cure times, allowing immediate testing and commissioning upon tightening.

Assembly requires only a standard cordless or manual ratchet driver with an 8 mm or 10 mm socket. With its compact mechanical joint profile, the fitting installs efficiently in tight chases and wall cavities where bulkier systems cannot fit. The collar assembly is modular and fully interchangeable with Georg Fischer Fuseal electrofusion collars, allowing seamless transitions between mechanical joint and electrofusion connections on the same fitting body.
