Forespar Marelon Ball Valve 3/4″

These Forespar ball valves feature NPS straight (parallel) threads at each end and are designed to be fitted with straight-thread thru-hull or pipe fittings.

Straight threads are not “self-sealing.” You must use pipe joint compound, thread seal compound, or Teflon® tape to seal the threads when making connections.*

An advantage of parallel threads over tapered threads, however, is that they allow maximum engagement between mating threads, providing an exceptionally strong connection.

These valves are made of exceptionally strong, fiberglass-reinforced Marelon®. Marelon is both electrically and chemically inactive, offering key benefits for marine applications:

• Easy Installation & Low Maintenance: Ensures a long service life for the end user, with zero risk of corrosion or galvanic electrolysis over time.

• Lightweight & Durable: Features exceptional UV resistance and will not freeze or become brittle with age.

• Certified Safety: Exceeds ISO standards, is approved by the ABYC, and passes the same stringent Marine UL tests required for bronze fittings.
