Holman 25mm PVC O-ring nipple joins female-threaded manifold and valve connections. The O-ring provides the seal at the connection.
Male threads at both ends connect female fittings or valve ports. The O-ring seals the matching manifold connection when tightened.
Made from UV-resistant PVC with high-impact construction and rated to 1000kPa.
Use matching Holman manifold nipples at swivel-to-valve connections and matching Holman manifold caps to close unused male ends. Standard threaded nipples and caps are not substitutes for these O-ring sealing components, even when the thread size matches. Keep the manifold, fittings, nipples and caps within the Holman system. Hand-tighten O-ring joints without thread tape.
