The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
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.
For use with Naylor Spiral Buttweld ventilating lines, this variation of the Naylor Hinged Wedgelock Coupling meets the requirements for an inexpensive yet air-tight connector. This quick-connecting and versatile coupling is available in sizes to 72”. The multiple hinge design with a one-piece ring gasket provides the leak-tight positive connection.
The Naylor Extra-Heavy-Duty Hinged Wedgelock Coupling is similar to Figure 1H and is designed to accommodate higher pressure applications and provide an efficient coupling for larger diameter lines. Accurately sized ends and gaskets, combined with a heavier cross section coupling channel extend the size and pressure range of this effective, economical connector.
1Lubricate pipe ends with water soluble lubricant and slide gasket over one pipe end.
2Bring pipe sections together and slide gasket over the joint. Lubricate outside of gasket with water soluble lubricant.
3Fit housing over gasket and close coupling into grooved ends of pipe.
4Insert wedge into the three lugs on coupling and drive it home with a hammer.
