TRAP ADAPTER,FEMALE,W/PLASTIC NUT WASHER;SJ×H

Specifications and Selection Tips

When choosing a PVC trap adapter, paying attention to the following specifications will ensure a proper fit and long-term performance:

Size and Compatibility: The most critical factor is the pipe diameter. PVC trap adapters come in standard sizes such as 1¼ inch, 1½ inch, 2 inch, and 3 inch to match different drainpipes and trap arms. Always measure your existing pipes before purchasing.

Material Standards: Look for products that comply with international standards for quality and safety. These often include:

ASTM D2665: Standard specification for PVC plastic drain, waste, and vent pipe fittings.

ASTM D1784: Standard for rigid PVC compounds.

NSF/ANSI 14: Certification for plastics components and related materials for use in potable water applications.

Temperature and Pressure Ratings: PVC fittings are typically rated for continuous use within a specific temperature range, often from -20°F to 140°F (-29°C to 60°C). They are generally designed for gravity-flow (non-pressurized) drainage systems.

Advantages of Using PVC Trap Adapters

PVC is the dominant material for these fittings due to several beneficial properties:

Corrosion Resistance: Highly resistant to many inorganic chemicals, as well as solutions of acids, alkalis, and salts commonly found in household waste.

Durability: Offers good mechanical strength and abrasion resistance for a long service life.

Non-Toxic: PVC-U is non-toxic and taint-free, making it suitable for potable water and food-related uses.

Ease of Installation: Joints are typically made with cold solvent welding (using PVC cement), which creates a strong, permanent bond without the need for open flames or specialized tools.

Types of PVC Trap Adapters

Slip-Joint Trap Adapter

Has a nut and washer for a slip-joint connection to the P-trap.

Often used with 1.5-inch (common for sinks) or 2-inch (for larger drains) pipes.

Threaded Trap Adapter

Has male or female threads to screw into a threaded drain pipe.

Used when the drain line is already threaded.

Glue-On (Solvent Weld) Trap Adapter

Designed to be cemented (glued) onto PVC pipe.

Provides a permanent, leak-proof connection.

Trap Adapter with Union Nut

Allows for easy disassembly of the P-trap for cleaning.

Common Uses

Connecting a kitchen or bathroom sink P-trap to the drain line.

Adapting between metal tailpieces and plastic (PVC/ABS) drain pipes.

Repairing or replacing old trap connections.

Installation Tips

Measure the pipe diameter (usually 1.25", 1.5", or 2").

Choose the right type (slip-joint, threaded, or glue-on).

Use plumber’s tape (for threaded connections) or PVC cement (for glued connections).

Tighten the slip nut by hand first, then use pliers gently to avoid cracking.
