Lesso 1-1/2 Inch ABS P-Trap Adapter, 2 Pack
The Lesso ABS trap adapter is designed for 1-1/2 inch ABS drainage links between a sink and a trap. It uses SPG (spigot) x SJ (sink joint) connections, with a included plastic nut and washer to seal the joint. This product is best for users with ABS-based sink drains seeking a straightforward, ready-to-seal option. It is suitable for cold-water environments and offers corrosion resistance with high-impact ABS. Choose this if you want a compact, ready-to-install bundle for a single or multi-project setup.
Best for: DIY homeowners and small renovations needing a simple, two-pack solution. Better for: projects using ABS drain pipes with standard 1-1/2 inch traps. Avoid if: you require metal adapters or non-ABS materials for harsh chemicals.
Caution: Ensure the sink drain threads align with the SPG x SJ connection to avoid cross-threading; check local code for ABS compatibility in your region.

Better for: users prioritizing a reliable, corrosion-resistant PVC option. Caution: PVC fittings must be compatible with your local code for waste and vent piping.
Buying Guide: Key Considerations For Trap Adapters
- Material compatibility: ABS vs PVC. Choose ABS for rugged, hot-water drainage in ABS networks; choose PVC for corrosion resistance and common DWV tasks.
- Size and orientation: Ensure the adapter matches both the trap and sink drain sizes (commonly 1-1/2 inch). Check for SPG x SJ or slip-joint configurations as appropriate.
- Temperature rating: Most household drainage components tolerate up to 140°F (60°C). Verify local usage if hot water is frequent.
- Number needed: Bulk packs save time for multi-project homes or maintenance crews.
- Installation considerations: Look for built-in seals (nut and washer) to simplify installation and reduce leak points.
- Code and compatibility: Confirm that chosen materials align with local plumbing codes and the rest of the system (DWV, drainage, venting).
FAQ
- What does 1-1/2 x 1-1/4 mean in trap adapters? It describes the two ends of the fitting: one end fits 1-1/2 inch pipe, the other end fits 1-1/4 inch pipe, enabling a size reduction or connection between different pipe sizes.
- Which material is better for kitchen sinks—PVC or ABS? Both are common; choose ABS for rugged, heat-tolerant drain paths and cost efficiency in ABS networks, or PVC for broad corrosion resistance and DWV compatibility. Ensure system compatibility with existing pipes.
- Do these adapters come with seals? Many packs include a plastic nut and washer to seal the joint, but verify per product listing to ensure all required hardware is included.
- Can I use these adapters in hot water drainage? Most are rated up to 140°F (60°C); avoid high-temperature scenarios beyond the rating unless specified by the manufacturer.
- Are these fittings leak-proof? They are designed to seal with included hardware; proper tightening and alignment are essential to prevent leaks at slip joints.
- Is bulk buying advantageous? Yes, for ongoing maintenance or multi-sink renovations, bulk packs reduce the need to reorder and ensure parts are on hand.
