Description
Vacuum pumps like the Edwards E1 and E2M run hot and hard in labs or shops. They need parts that don’t quit. This stainless steel spring is one of those. It sits inside and gives just the right tension. Keeps blades or seals from slipping around.
Handles the full range – from E2M2 up to E2M30. Weighs a solid 1.00 pounds.
If your pump’s acting up, start with this. Small change, big difference. Keeps you going without the wait.
