Description

Astralpool Hurlcon threaded 3/8" M4 Brass Plug with Hex Head. Used for High-Limit Switches. Hi-Limit switch screws into these brass plugs.

They can corrode due to water quality, or where a small leak has allowed the 24V from the hi-limit switch to cause electrolytic corrosion.

Leaking brass plugs will cause failure of high-limit switches from corrosion.

Old ones had a 3/4" head and were 13-16mm long. New ones have a larger head, and are now 19-25mm long. They are all interchangeable. Later ones are better. Notice photo showing both the older style and newer style.

Shipped Fast from NSW, VIC, QLD. 
Pick-up is available from our office in Carrum Downs, Vic. 

It is important to replace or repair these when leaking, and should be checked every 6-12months. This can be one of the biggest causes of damage to gas heaters.

Suits: Later MX, HX, Viron, JX, ICI Heaters. Also suits Jacuzzi J-HN250C & J-HN400C heaters. 

Installing:
Use Pink Thread Tape or a chemical-resistant thread sealant for Sealing threads. Care must be taken not to cause radial cracks in the header manifold around the female threaded area. <-- This is usually caused by over-tightening.

The red fibrous gaskets are no longer used. Use Teflon tape on the thread.
