Vacuum Relief Valve Attachment Set w/ Rubber Hose Type Connector

A ball spring (5#) type check valve is typically installed at the highest point in a solar pool heating system. By allowing air to enter the pool solar panels, it aids in gravity drainage of solar pool collectors and piping. Internal components feature a Viton o-ring, glass-reinforced ball, and 5# stainless steel spring. Panel connector hose is molded EPDM rubber designed specifically for use with solar pool heating systems. Durable UV-resistant EPDM rubber for long life in direct sun. Reinforced center prevents deformation from pressure and vacuum. Hose-clamp indicator ridges for perfect placement and seal. Hoses are 3.75" wide. Hose Clamps are stainless steel construction for optimal strength and corrosion resistance. Compatibility: Will work with any solar pool heating system that has round 1.5” or 2" I.D. header manifolds and makes attachments with rubber hose type connectors. Measurements & Sizing 1.9" (1-7/8") O.D. Vacuum Relief Valve Connector Set:  For solar pool panel
