    Overview

    The Marelon Integrated System valves were specifically designed for production boat builders. They offer more configurations and options than any other brand/style valves made for the marine industry. Forespar can thread match the flanged bases to fit NPSM (NPT Parallel) in 3/4" through 2" or BSP from 1" through 2" for use on bronze or stainless thru-hulls. Forespar's complete system comes with a flush or mushroom head "buttress" threaded thru-hull for exceptional strength. When the complete system is used Forespar supplys an emergency thru-hull plug as a cap in the handle. This plug can be used if needed by plugging the thru-hull from the outside to allow full disassembly of the valve to clear a clog or replace the entire body all without having to haul the boat. All configurations meet or exceed ABYC standards, are U.L. Approved and ISO Certified.

    Features:

    • The Forespar® 93-Series Valves with Thru-hull Fitting Assemblies is a complete system
      • Includes thru-hull fitting, valve body, and hose connector
    • Thru-Hull Material: Marelon
    • Rated for Above / Below Waterline
    • OEM Replacement
    • Will not Rust or Corrode, Discolor or Contribute to Electrolysis
    • Meet all design criteria
    • Exceed all mechanical property requirements specified by the international standards organization
      • (ISO 150/188) "Small craft-seacocks and thru-hull fittings-part 2: Non-metallic"
    • Exceeds standards for use set by the U.L. (Underwriters Laboratory) and the American Boat and Yacht Council (A.B.Y.C.)
    • 93-Series Thread Form
      • The thread form used on these thru-hull fittings and king-nuts is a non-tapered buttress type of thread design
      • This thread form has a higher load carrying capacity, particularly for polymeric materials
      • Warning: a standard pipe threaded thru-hull fitting will not fit with the king-nut on these valves
        • For a standard pipe threaded thru-hull fitting, use Forespar valves that have standard female pipe thread outlets instead of a king-nut base
      • A buttress thread design with the same amount of clearance as for a conventional pipe thread will give the impression of greater looseness
        • However, when the joint is taken up tight, there is a greater area of surface between threads with the buttress thread form
      • As with any threaded pipe assembly , Teflon® tape should be applied to the thru-hull threads for a watertight connection
