Pool Expansion Plugs
Use these FREEZE PLUGS to plug the pool pipes after draining or blowing them out. American made, stainless steel bolts and washers with Delrin wing-nuts. Premium winter pool plugs for winterization, these rubber plugs are also used to plug pipes or equalizer lines when leaking, or for pressure testing pipes.
Extended plugs have a 3in long screw and sleeve which covers the screw and extends the reach of the plug into the pipe. No. 4 or #4 Extended freeze plugs are used for plugging slip (not threaded) wall returns that are cut at an angle, and #8 extended plugs are useful for plugging spa return jets or plugging main drains in combination skimmers, used in single hole skimmers that have the main drain connected, like Anthony or Sylvan pools.
Winter pool plugs, aka Freeze Plugs are rubber expansion plugs that expand when you tighten the wing nut. Stainless steel bolt and washer won't rust, and the oversized nylon wing nut is easy to grip - even in very cold water! Replace your pool plugs when they show signs of dry-rot, usually after about 3-4 winters.
Number 4 Expansion Plug for 3/4" and 1" Pipe.
Use the Extended #4 winter plug on pool wall returns that are cut at an angle to the pool wall. This winterizing plug is made from high quality rubber and features a wing nut that turns easily to create a tight seal around the pipes, and is meant for easy installation and removal, on angled wall returns.
Number 8 Extended Expansion Plug for 1-1/4" and 1-1/2" Pipe.
Use the Extended #8 winter plug on spa jets, or to plug the main drain pipe, when connected to a skimmer. Also fits deep into 1.5" wall returns and skimmers. Also used on in-floor cleaner system pipes. Where ever you use a regular #8 plug, the extended version is easier to work with and gives a better seal, further into the pipe.
