content: Hi guys,My ZD-915 desoldering station stopped doing his job and will not sucker solder anymore.Unfortunately I have figured put what the problem is. After my last gun cleaning I did not pay attention but a rubber sealant on the gun has gone probably into the bin and trashed by mistakeIn the picture attached here you can see the area where this black rubber sealant is supposed to sit.Is there any spare of this part i can purchase somewhere or at least search for a substitute?Many thanks and happy New Year to everybody !

content: 3D print ?Thermoplastic elastomers (TPE) are the best category of filament material for flexible tires. TPE filaments have very similar properties to rubbers which are the most common material for tires. Ninjaflex and Fiberflexare two of the best TPE brandsThermoplastic Polyurethane (TPU) is a flexible, abrasion resistant thermoplastic which better withstand impacts, also resistant to many chemicals, and exhibits greater rigidity, not to be confused with hardness, also has a smooth finish, and shrinks less than TPE, but TPE burns with a faint aroma whereas TPU burns with an irritating odor.

content: I was indeed thinking to find a standard round rubber that could fit but this part is placed in contact with the pipe connected directly with the heater. Those rubber parts should be also high temperature resistant.

content: And by the way you can increase the suction force and minimize glogging by putting an Eurocent coin in the middle of the glas tubeand exchange the metal plate at the filter side with a sieve from a perlator...

content: Quote from: giovannirat on April 05, 2022, 07:18:37 amAm I correct in assuming that any 1 cent coin would do as long as it is not as big as the inside of the glass tube? Since percolators are mostly a thing of the past (at least here in the USA) what mesh is that screen? Or am I wrong and perlator is not a coffee percolator?My ZD915 just does not have enough suction to clean out a pin (like an IC pin). I have tried to find a replacement vacuum pump that will fit the ZD915 but more suction and does not cost a fortune! Has anyone found such a replacement pump source?Thank you.

content: Quote from: giovannirat on April 05, 2022, 07:18:37 amI understand the why of replacing the metal plate at the back of the chamber in front of the filter with a water tap screen. What is the purpose of the coin in the middle?
