Description
This is an original Leybold plug screw. It is used to seal unused ports or openings on the pump. It’s a simple but important part for keeping your system leak-free and tidy. This plug screw is designed for that job. You simply screw it tightly into the unused port. It blocks the hole completely. This keeps the inside of the pump sealed off from the outside air.
This might look like an ordinary screw, but it is made to Leybold’s specifications. It has the exact right thread size and pitch to match your pump’s ports. Using a hardware store bolt might not fit perfectly. A poor fit can still leak air or, worse, damage the threads in your expensive pump.
Having a few of these on hand is smart for any technician. They are used to close off ports after removing an accessory or during a pump rebuild. It’s a small part that makes sure your system stays airtight.
