This pack of three 1", 20 in long pinch hoses is essential for pinching off abrasive flow from the pot to the blast hose in your DB500 or DB800 blast pot and should be replaced monthly or after four rotations to ensure optimal performance.
Note: Replacement two-lug KF hose couplings are not included. Get a pinch hose with pre-screwed couplings here, or shop just the two-lug KF hose coupling here.
