Watch for a damp patch or mineral staining directly under the heater tube, white crusting on the union nut, corrosion creeping onto the heater terminals or element studs, or an RCD that trips intermittently once the heater has been running.

Do not over-tighten the union nut — these seal on the rib, so hand-tight plus about a quarter turn is enough.

Colour reflects the moulding batch, not the specification.\u003c\/p\u003e\n\n\u003cp\u003eWhy does a \"50mm\" gasket measure 74mm?\u003cbr\u003e\n50mm is the nominal pipe name, not a measurement. A 50mm pipe is about 60-61mm OD, and the union face the gasket seals against is larger again. Measure the old gasket, not the pipe.\u003c\/p\u003e\n\n\u003cp\u003eWhich side faces the heater tube?\u003cbr\u003e\nThe raised rib faces the heater tube flange; the flat side sits against the union tailpiece. Fitted backwards it will usually still seal, then weep once it heat-cycles.\u003c\/p\u003e\n\n\u003cp\u003eDo I need two?\u003cbr\u003e\nYes. A heater tube has a union at each end, and both should be replaced together. That is why this is sold as a pair.\u003c\/p\u003e\n\n\u003cp\u003eMy pack is Sig10 or an SCS 501. Will this fit?\u003cbr\u003e\nYes. The Sig10, Sig10L, SCS 500, SCS 501, GS501 and VS500 all use the 2\" flo-thru heater and take this gasket, as does the GS501z that replaces them.\u003c\/p\u003e\n\n\u003cp\u003eMy spa is a rebadged brand, not a Balboa. Will it fit?\u003cbr\u003e\nAlmost certainly, if the heater has 2\" unions. Most Australian spa brands buy a Balboa, Gecko or Gecko-pattern pack and put their own badge on the box. Measure the old gasket at 74mm and order with confidence.\u003c\/p\u003e\n\n\u003cp\u003eCan I reuse the old gasket if it looks fine?\u003cbr\u003e\nNot recommended. A gasket heat-cycled for years has lost rib height even when it looks intact, and a slow union weep will quietly corrode the heater terminals and the pack sitting under it.\u003c\/p\u003e\n\n\u003cp\u003eDo I need to drain the spa to change these?\u003cbr\u003e\nUsually only below the heater line. Isolate power first, close any shut-off valves, and have a towel ready — there will be water in the heater tube itself.\u003c\/p\u003e\n\n\u003ch3\u003eCommon search terms\u003c\/h3\u003e\n\n\u003cp\u003eo-ring, oring, Balboa heater gasket, 50mm spa heater seal, 2 inch heater union seal, Gecko heater gasket, AEware heater gasket, spa heater o-ring, 74mm heater gasket, Balboa 21619, 711-4031, spa heater union washer, Sig10 heater gasket, SCS 501 heater seal, SpaPro heater gasket, WWDG heater gasket.\u003c\/p\u003e\n\n\u003c!-- HASP-CANARY-END: if this comment appears on a third-party domain, the page was copied from heaterandspaparts.com.au --\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@graph\": [\n    {\n      \"@type\": \"FAQPage\",\n      \"about\": \"Balboa 74mm 50mm spa heater union gasket fitment\",\n      \"publisher\": {\"@type\": \"Organization\", \"name\": \"Heater \u0026 Spa Parts\", \"url\": \"https:\/\/heaterandspaparts.com.au\"},\n      \"mainEntity\": [\n        {\"@type\": \"Question\", \"name\": \"Does it matter if the spa heater gasket is black, white or clear?\",\n         \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. Balboa and Gecko have used all three colours.

The 58118 is an earlier stud-and-nut version with longer sensor leads and is commonly associated with the older copper-lug connection.

Do I need a new heater?\u003c\/strong\u003e\u003cbr\u003eNot necessarily. HFL and LF indicate inadequate water flow or an excessive temperature difference between the M7 sensors. Check the water level, filter, suction fittings, isolation valves, pump prime and trapped air before replacing the heater. The M7 system requires approximately 23 GPM through the heater tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need the titanium version?\u003c\/strong\u003e\u003cbr\u003eThe titanium version is generally selected for aggressive water conditions, including bore water, high sanitiser levels or coastal installations.
