This fitting ensures that your plumbing remains secure even in the most demanding maritime environments.

Engineered from premium #316 stainless steel, this fitting offers superior corrosion resistance in harsh saltwater environments compared to standard bronze or nylon alternatives. The THXL-2000-WS features a unique extra-long NPSM / NPT combination thread, allowing for versatile plumbing connections while ensuring a secure, watertight seal against the hull.
