SWEP Gaskets & Plates: Compatibility Guide
SWEP Gaskets & Plates: Compatibility and Replacement Guide
Most SWEP plate heat exchanger gaskets inquiries start with a size. The first thing worth checking is whether the unit has gaskets at all. SWEP builds brazed and gasketed ranges, and used units often arrive without paperwork.
Gasketed or Brazed?
Brazed plate heat exchangers have no gaskets. The SWEP B range (B3, B5, B12, B25 and the rest) is vacuum-brazed into a sealed block, with no gaskets and no frame, so a leak means repair or replacement. Gasketed SWEP units carry other prefixes: G, GX, GC, GF, and the HX, MF and UX families. Check the prefix before you search for swep plate heat exchanger gaskets.
Reading the Model String
Knowing how to identify a SWEP heat exchanger comes down to the tag. The full string carries the family, the plate pattern, the connection type and the pressure class. Two units with the same prefix can still take different plates. Shoot the nameplate square on, then a close frame with every character readable. A SWEP GX gasket order needs that plate detail, since one family covers several plate widths and port layouts.
Clip-On or Glued
Gaskets come in clip-on and glued form, and this is where most wrong orders begin. The clip version is held by moulded tabs and lifts off by hand. The glued version is bonded into the groove, and the old adhesive must be scraped out before refitting. The two are not interchangeable on one plate. A photo of the plate edge, showing tabs or a bare groove, settles it.
Plates and Gaskets as a Set
Plates wear at the port and in the groove, so a swep gasket replacement on a tired plate can leak again within weeks. When both are changed, the plate pattern and the gasket profile have to match as a pair. Mixing plates from a similar model is the usual reason a pack will not close to its A-measurement.
What to Send
For swep plate heat exchanger spare parts, four items cover most checks: a nameplate photo, a plate edge photo, the current plate count, and the medium with its operating temperature. Add the A-measurement if the unit is already open. With those, the reply is a check against a known pattern.

FAQ
Q: My tag says B25. Can I buy gaskets for it?
A: No. B25 is a brazed unit with no gaskets. Send the tag photo and we will confirm the range.
Q: The old gasket has no tabs. Does that mean glued?
A: Most likely. A photo of the plate edge and the groove confirms it.
