Meet the Green Leaf Nylon 3/8 in. D X 3/8 in. D Nipple — a compact, lead-free connector designed for dependable, corrosion-resistant connections in a range of piping and pneumatic projects. With male threads on both ends (MPT to MPT) and a 3/8 in connection diameter, this nylon nipple slides into standard systems with ease, delivering reliable performance where it matters most.
Why nylon makes sense for fittings
Nylon offers a lightweight, durable option that resists rust and chemical wear, helping your connections last longer in everyday setups. The material’s natural lubricity aids smooth thread engagement, reducing the chances of cross-threading and wear over time. Plus, the lead-free composition provides a safer choice for projects where contamination concerns are a consideration.
