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. Any of those means the gasket has taken a compression set and is weeping under thermal cycling.\u003c\/p\u003e\n\n\u003ch3\u003eWhen to replace\u003c\/h3\u003e\n\n\u003cp\u003eReplace both gaskets as a pair every few years, and always after a chemical imbalance event or any time the heater tube is removed. Ribbed gaskets lose rib height with heat cycling even when they look intact, so replacing one and reusing the other is a false economy. Do not over-tighten the union nut — these seal on the rib, so hand-tight plus about a quarter turn is enough. Over-tightening splits the union collar and turns a $11 job into a heater tube.\u003c\/p\u003e\n\n\u003ch3\u003eReplaces \/ may be stamped as\u003c\/h3\u003e\n\n\u003cp\u003e711-4031, 21619, B-21619, B21619, RGASHEA50M, PL-10170.\u003c\/p\u003e\n\n\u003ch3\u003eFits these Balboa heater tube part numbers\u003c\/h3\u003e\n\n\u003cp\u003eAll standard 15\" x 2\" Balboa M7 and non-M7 heaters, including: 26-58083-K, 26-58118-K, 50096, 50139, 53475, 53475-01, 53883, 53883-01, 53883-02, 53883-03, 53883-04, 53885, 53885-01, 53885-02, 53885-03, 53885-04, 53996, 54282, 54282-01, 54282-02, 54282-03, 54282-04, 54297, 54297-01, 54297-02, 54297-03, 54305, 54305-01, 54305-02, 54346, 54346-01, 54406, 54476, 54476-01, 54479, 54479-01, 54479-02, 54501, 54501-01, 54503, 54503-01, 54699, 54705, 54850, 54850-01, 55085, 55085-01, 55087, 55087-01, 55496, 55496-01, 55565, 55595, 55595-01, 55614, 55626, 55866, 55866-01, 55890, 56002, 56002-01, 56002-02, 56002-03, 56002-04, 56004, 56004-01, 56012, 56012-01, 56012-02, 56220, 56282, 56290, 56290-01, 56911, 58053, 58061, 58061-TUV, 58063, 58083, 58107, 58118, 58118KIT1, 58122, 58141, 58143, 58145, 58215, 58300 Series, 58301, 58306, 58433, 58450, 58454.\u003c\/p\u003e\n\n\u003cp\u003eAlso fits the Balboa Auxiliary Slave Heater and SCS 501 assemblies.

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.
