1900AB LF Dielectric Union

The 1900AB LF Dielectric Union is engineered to isolate dissimilar metals in piping systems, eliminating electrolytic corrosion between copper, steel, and other metals. Featuring a forged steel body and low-lead brass tailpiece, this union meets rigorous safety standards for potable water while ensuring long-term reliability in high-pressure environments.

Key Features & Benefits:

✅ Dielectric Isolation – EPDM seals and insulating gasket prevent galvanic corrosion between metal pipes.
✅ 200# WOG Pressure Rating – Built to withstand 200 PSI for water, oil, and gas applications.
✅ Hybrid FNPT x Solder Ends – Combines threaded (FNPT) and solder connections for versatile installations.
✅ Forged Steel Construction – Heavy-duty body resists deformation under stress for enhanced durability.
✅ Certified Compliance – AB1953 and NSF/ANSI 61 & 372 certified for safe drinking water systems.

Technical Specifications:

• Body Material: Forged steel with low-lead brass tailpiece.
• Seals/Gasket: EPDM (temperature-resistant, chemical-proof).
• Ends: FNPT (Female National Pipe Thread) x Solder.
• Standards: ANSI/ASME B16.39 compliant.
• Pressure Rating: 200# WOG (Water, Oil, Gas).

Ideal Applications:

• Connecting copper to steel pipes in HVAC and plumbing systems.
• Industrial process lines, potable water distribution, and gas pipelines.
• Municipal and commercial projects requiring corrosion prevention.
