ANTI-CORROSIC ABS PLASTIC - The two-way ball valve is made of high-quality ABS material, which is durable and UV-resistant. Unlike metal ball valves, the stem will not have any corrosion or clogging problems. Some parts are replaceable, such as the stem, ball, O-rings, handles, and connectors. PERFECT REPLACEMENT - Econoline replacement two-way ball valve. This two-way ball valve is compatible with Hayward PN.SP0729 pool filter. It differs from other Hayward ball valves because it includes a hose adapter. Note: This is a replacement part manufactured by JYNTERPLAY to OEM quality standards (based on internal testing). We are not affiliated with or endorsed by any of the manufacturers mentioned, including Hayward. FULLY COMPATIBLE: The 1.5-inch male threaded end connects to a Hayward filter, pool hose, or skimmer with a 1.5-inch pump and a 1.5-inch female thread, while the 1.5 and 1.25-inch hose adapter ends connect to 1.25 or 1.5-inch hoses.
