This pack of three 1", 20in 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.
