How is the size of the tubular product determined for each application?
The most common tubular product sizes are 1¼” and 1½”. These sizes are available in brass and plastic tubular products. The trap adapter connection to the branch drain in the wall will determine the largest size of tubular product which can be connected with a slip nut and washer. This point of connection can also be reduced for 1¼” tubular assemblies, with a reducing washer and slip nut. Bathroom sink installations are normally completed with 1¼” tubular products, but 1½” tubular products will also work. Kitchen sink installations can only be completed with 1½” tubular products.
What makes the True Blue slip joint washer better than others?
True Blue is IAPMO listed. True Blue won’t dry out or crack. This ensures long, leak-free protection. True Blue has superior flex fatigue protection, which extends the life of the washer. True Blue has advanced Thermoplastic Elastomer (TPE) properties. This allows the True Blue to retain its shape when the traditional polypropylene washer may not. Overall; the Ultra flexible elastomer washer combined with the tapered design, provides the end user with ultimate leak protection.
