Lasco 436-251 is a Schedule 40 PVC reducing male adapter engineered to provide a reliable transition between 2" and 1-1/2" pipe sizes. Combining a threaded male end with a solvent-weld slip socket, this adapter is built for plumbing, irrigation, pool and spa systems where a durable, corrosion-resistant connection is required.

  • Reliable Schedule 40 PVC construction. Injection-molded PVC offers chemical and corrosion resistance for long service life.
  • 2" MPT (male) x 1-1/2" slip socket. Threaded end mates with 2" female threaded fittings; slip end accepts 1-1/2" pipe using PVC primer and solvent cement.
  • NSF/ASTM compliant. Meets common standards for potable water and pool applications when used per manufacturer guidelines.
  • White finish and compact profile. Blends with standard PVC piping and minimizes flow disruptions with smooth internal walls.
  • Recommended temperature range. Rated for typical PVC service up to about 140°F; avoid use with compressed air or gases.

Installation is straightforward: apply compatible PVC primer and solvent cement to the slip socket, and use PTFE tape or pipe dope on the male threads for a pressure-tight threaded connection. This adapter is offered as individual units and in case quantities to suit contractor and DIY needs.
