4" x 3" in Thread Size 80 Reducer Nipple | 62938

Product Introduction — 4" x 3" Thread Size 80 Reducer Nipple (62938)

The Barr Plastics 4" x 3" Thread Size 80 Reducer Nipple (model 62938) is a threaded plumbing fitting that connects a 4" pipe to a 3" pipe with secure, leak-resistant male threads on both ends. Made from durable plastic (typically PVC), this reducer nipple resists corrosion and chemical degradation, making it ideal for plumbing, drainage, and irrigation systems. Designed for quick installation into size 80 female-threaded fittings, it simplifies pipe transitions without the need for special adhesives.

Features & Specifications

• Product code: 62938 — easy ordering and part reference
• Size: 4" nominal diameter on one end → 3" nominal diameter on the other end
• Thread standard: Thread Size 80 — compatible with other size 80 threaded fittings
• Material: Durable plastic construction (typically PVC) for corrosion and chemical resistance
• Connection type: Male threads on both ends for screw-in installation to female-threaded pipes or fittings
• Installation: Threaded connection — use PTFE tape or pipe thread compound for optimal seal
• Applications: Plumbing, wastewater, irrigation, drainage, and light industrial piping

Benefits & Applications

The 4" x 3" Thread Size 80 Reducer Nipple (62938) solves the common problem of joining mismatched pipe diameters quickly and reliably. Its threaded design allows fast installations and easy future disassembly for maintenance or changes. The plastic construction minimizes corrosion and chemical attack compared with metal alternatives, extending service life in wet or chemical-exposed environments.

Use this reducer nipple in residential and commercial plumbing, septic and wastewater systems, irrigation networks, and many light industrial piping setups. For example, it provides a smooth transition from a 4" main drain to a 3" branch line in irrigation systems, helping maintain flow control while simplifying piping layouts. For best results, verify thread compatibility and system pressure/temperature requirements before installation.

Installation & Maintenance Tips

• Apply PTFE tape or pipe thread compound to male threads before assembly for a leak-resistant seal.
• Hand-start threads to avoid cross-threading, then tighten with a wrench until snug—do not over-torque.
• Inspect threaded joints periodically for wear or leaks, especially in high-vibration or high-flow systems.
• Clean debris and buildup from inside fittings as needed to maintain full flow capacity.
