The Naylor Heavy-Duty Hinged Wedgelock Coupling shown in
Figure 1H is a variation of the Naylor standard one-piece heavy-duty
coupling and offers additional advantages for both permanent and
temporary lines. While retaining the simplicity and speed of the standard
Wedgelock, the hinged coupling introduces greater flexibility to broaden
the use of this versatile connection. The continuous ring gasket provides the
seal to withstand the stresses and strains of expansion and contraction in
prolonged service. The hinged design and ease of operation offer users
the opportunity to replace uniform pipe lengths and/or rotate a number of
lengths without disturbing the balance of the line.
