Tranter Gaskets & Plates: Replacement Essentials
Tranter Gaskets & Plates: Replacement Essentials
A Tranter tag rarely says just GX-42. It says GXD-042-H-7-UP-102, and every block changes what must be ordered. For tranter plate heat exchanger gaskets, the tag is the specification.
Read the Tranter Superchanger Model Number First
GXD-042-H-7-UP-102 has six parts. GX is the plate style. D is diagonal flow, P parallel. 042 is the plate model. H is the chevron angle; L and M are alternatives. 7 is plate thickness in tenths of a millimetre. UP is the frame, and 102 is the plate count. Two units of the same size can differ in angle, thickness and plate count.
Which Plate Series You Have
The range splits by where the gasket groove sits. GX (Ultraflex), GL and GF carry it in the plate's neutral plane. GC (Conventional) carries it in the bottom plane, so a full-thickness gasket is glued to the front of each plate.
Glued, Clip-On or Superlock
Glued gaskets are the standard. A tranter clip-on gasket needs no adhesive or tools: it clips to the plate edge and lifts off whole, which suits units opened often. Tranter lists clip-on for a limited set of plates, including GX-26, GX-42, GC-8, GC-26 and GL-13, four of which accept either style. Superlock is a third option on selected plates. A glueless gasket will not seat on a plate cut for glued gaskets, and the reverse is just as wrong.
Old Names Still on Tags
Older names still appear: a tranter gc gasket ordered as GC-12 is now quoted as GCD-012, GC-26 became GCP-026, and older 06-T sizes still turn up. Send the tag as it reads, and identify the plate by pattern and footprint, not by the old label.
The Half-Thickness Detail
On GX, GL and GF packs, the first and last plates take a half-thickness gasket, and so does the partition plate in a multi-pass unit; a standard set leaves those wrong.
What to Send for a Tranter GX42 Gasket
Five items cover the check: a nameplate photo, a plate edge photo showing the groove and any clips, the plate count, the A-measurement if the unit is open, and the medium and its operating temperature. Those five get a matched answer; a model name does not.
Send the tag and plate photos to info@newroc-phe.com and we will check the pattern against the drawing.
FAQ
Q: My tag says GXD-042. Is that the same as GX-42?
A: Yes, GX-42 is the short form. Keep the full string, with the angle letter and plate count, on the order.
Q: Can clip-on gaskets go on any Tranter plate?
A: No. Only specific ones. Plates cut for glued gaskets need glued gaskets, and a few models accept both.
