EHLE-X-Trakt Replacement Set — spare frit and o-rings
The EHLE-X-Trakt Replacement Set is a spare-parts kit that restores a broken or worn EHLE-X-Trakt glass extractor to working order. Inside the box: one fritted glass filter disc and two silicone o-rings. That's it — no tools, no extras, just the two parts that actually give up on you first.
Why this replacement set exists
Because glass breaks and rubber wears out. The EHLE-X-Trakt is a high-end closed-column extractor made entirely of borosilicate glass, with a sintered glass frit doing the filtering work at the bottom. Drop the column on a tiled floor, over-tighten the assembly, or run it too many cycles without cleaning — and the frit cracks or clogs. Lose an o-ring down the sink during a rinse and the seal's gone. Either way, the whole extractor is sitting useless on the shelf.
Rather than replacing a EUR 80+ piece of glass over a EUR 2 rubber ring, you swap the part that failed. That's the whole point. We've been selling EHLE glass since the early days and the frit-plus-o-ring combo is far and away the most-asked-for spare — so much so that EHLE bundles them together as one set.

How to fit the replacement parts
- Disassemble your EHLE-X-Trakt completely. Rinse and dry every section — no residue left behind.
- Remove the old frit disc from its seat. If it's cracked, take care with the shards.
- Seat the new fritted glass disc in the filter chamber, flat side down, centred.
- Remove any old or damaged o-rings from the joints. Wipe the grooves clean.
- Fit the two new silicone o-rings into their seats. Don't stretch them — roll them on.
- Reassemble the column hand-tight. Over-tightening is what broke it the first time.
- Do a cold dry-fit test before any solvent goes near it. Check the seals hold.
Honest limitations
This set only replaces the frit and two o-rings. If you've cracked the column itself, the reducer, or the collection chamber, this set won't help you — you'll need a full replacement extractor. Also worth saying: the frit is a single universal disc that fits the standard EHLE-X-Trakt. If you've got a custom or older variant, measure before ordering. The o-rings are silicone, not Viton — fine for standard use, but if you're working with aggressive solvents beyond the intended purpose of the extractor, that matters.
Complete your setup: if the column itself has gone, grab the full EHLE-X-Trakt Glass Extractor to replace it. For cleaning the frit between runs (which extends its life dramatically), a bottle of iso 99% and a soft glass brush do the job.
From our counter
Nine times out of ten when someone brings in a "broken" EHLE-X-Trakt, it's one of these two parts. The frit clogs up because it wasn't cleaned properly between runs, then cracks under pressure on the next cycle. Or an o-ring gets stretched during disassembly and loses its seal. Keep a spare set in the drawer and you'll save yourself an emergency order every few months. We've seen customers keep the same glass column running for years on two or three frit swaps — that's the value here.
Frequently Asked Questions
Will this fit my EHLE-X-Trakt size S/M?
Yes — the replacement set is the original EHLE part and fits the standard EHLE-X-Trakt range including the S/M. If you have a much older or custom variant, measure the frit diameter before ordering to be safe.
Can I just use any generic o-ring?
Technically yes, practically no. Generic o-rings often aren't solvent-grade silicone and can swell, leak, or contaminate your extract. The EHLE o-rings in this set are matched to the column grooves — use them.
How do I clean the frit so it lasts longer?
Soak the disc in warm 99% isopropyl alcohol for 15–30 minutes after each run, then rinse and air-dry. Avoid dishwashers, harsh scrubbing, or sudden temperature changes — thermal shock cracks sintered glass.
Why did my frit crack in the first place?
Usually one of three reasons: clogged pores causing pressure build-up, over-tightening the assembly, or thermal shock from cold solvent hitting a warm disc. Clean between runs, hand-tighten only, and let parts equilibrate to room temperature.
Do I get one or two frits in the set?
One fritted glass filter disc and two o-rings. The o-rings wear out roughly twice as fast as the frit, which is why EHLE pairs them this way.
Is the frit made of the same glass as the column?
Yes — sintered borosilicate glass, the same material family as the rest of the EHLE-X-Trakt. That matches thermal expansion across the whole assembly and keeps the seal stable.
