Sea Tech 81902634 AquaLock Cone Seal Plastic Fitting 1/2" NPT to 1/2" NPS

The Sea Tech 81902634 AquaLock plastic fitting provides a reliable cone seal connection for transitioning between 1/2" NPT and 1/2" NPS thread types in marine plumbing applications. Manufactured by Watts, this fitting is constructed from polysulfone, a high-performance thermoplastic material known for its excellent resistance to heat, chemicals, and stress cracking.

Key Features:

• Polysulfone construction for superior durability and long service life
• Cone seal design ensures leak-free connections without thread tape
• Converts 1/2" NPT (National Pipe Thread) to 1/2" NPS (National Pipe Straight)
• Resistant to corrosion, making it ideal for saltwater and freshwater marine systems
• Withstands high temperatures and pressure cycling
• Lightweight alternative to brass fittings without sacrificing strength

AquaLock fittings are engineered for trouble-free performance in demanding marine environments, including potable water systems, bilge systems, livewell plumbing, and general boat plumbing applications. The cone seal technology eliminates the need for sealants while providing a secure, vibration-resistant connection.
