If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Installation length: approx. 160 mm
Mounting rings: Glass fiber reinforced plastic (GFRP)
This PTFE compensator DN25 is a compact, chemical-resistant solution for low-voltage connection of glass apparatuses after Normag-Standard in the small diameter range.
The system consists of the parts shown in the pictures.
By using pure white PTFE, GFK Mountings and Stainless steel components Is this compensator suitable for aggressive media as well as thermally and mechanically stressed applications – e.g., in laboratory reaction systems or in sensitive process technology.
Advantages:
- Highest chemical resistance through folded PTFE bellows
- Effective voltage balance & vibration isolation for glass connections
- Compact form factor: Ideal for tight construction spaces and lab setups
- Standard connection: Flange connection for glass to DN28 (Normag-compatible)
- Sustainable solution: Used, but very well preserved
- Ready for immediate usePre-assembled with stainless steel springs, screws and protective caps

⚙️ 2. General functions
- PTFE compensator for flexible, strain-free connection of glass pipelines
- Suitable for Vacuum, Overpressure as well as Temperature applications
- Reliable compensation axial, lateral and angular movements
- Designed for high chemical resistance in the laboratory environment
- Mounting length: approx. 160 mm
- Yellow protective caps pre-assembled on both sides for seal protection
Material structure:
- bellows: Pure, faced PTFE (white)
- Halteringe: Fiber-reinforced plastic (FRP)
- Connection: Stainless steel V2A with springs & nuts

? 3. CO₂ savings
By purchasing this used component, energy- and resource-intensive new production is avoided.
Estimated CO₂ savings:
? 100–140 kg CO₂
➡️ Approximately equals:
- the CO₂ emissions of a compact car on 900–1,100 km trip
- or the Power consumption of a 2-person household over about 2.5 weeks
