Ophjerg Dual Plunger Valve Kit for Intex Pools — 1.25" to 1.5" Hose Adapter B, Two On/Off Valves & O-Rings

Ophjerg Dual Split Plunger Valve with Hose Adapter B lets you shut off flow and convert 1.25" pool fittings to 1.5" quickly for Intex-compatible above ground filter pumps.

Maintain and adapt your above-ground pool plumbing without fuss: this two-valve kit includes two plunger-style on/off valves, replacement O-rings and step washers, plus two 10722/25009 hose adapters so larger pumps and hoses fit correctly. Engineered to work with Intex 1500, 2500 and 4000 GPH pumps and compatible chlorinator combos, the kit also suits many other above-ground systems that share the same inlet/outlet dimensions.

How does the plunger valve stop water when I need to change a filter?

The plunger-style on/off valves provide a simple manual shutoff built into the hose line so you can isolate the pump or filter without emptying the system. Pulling or pushing the plunger blocks the water path, making swaps and maintenance faster and cleaner.

• Two plunger valves let you isolate both pump inlet and outlet.
• Durable plastic construction resists pool chemicals for longer service life.
• Includes replacement O-rings and step washers to maintain a watertight seal.

Will this adapter let a larger Intex pump connect to my existing hose?

Yes — the included Hose Adapter B converts common 1.25" Intex fittings to 1.5" so you can upgrade to higher-flow pumps without needing entirely new plumbing. This is particularly useful when switching from 1000 GPH class pumps to 1500 GPH or larger models.

• Adapter part numbers 10722/25009 fit standard Intex outlet threads.
• Works with 1.5" hoses and 1.5" hoses having 2.5" threaded connector fittings.
• Two adapters in the pack allow both inlet and outlet conversions when upgrading pumps.

How do I install these valves and adapters — do I need extra tools?

Installation is straightforward and typically tool-free for most above-ground pool setups. Slide the hose onto the valve, position the washer and O-ring for a tight seal, then push the adapter into the inlet/outlet and secure threaded connectors where needed.

• Attach 1.5" hoses or hoses with 2.5" threaded fittings to the plunger valve lower end.
• Fit the 1.25" to 1.5" adapter to the pool or pump connection to complete conversion.
• No specialized plumbing tools required for typical installations; hand-tighten threaded fittings.

What pump and pool models is this compatible with?

This Ophjerg kit is designed to match the connection sizes used by many Intex pumps and accessories, including 1500, 2500 and 4000 GPH filter pumps and Intex saltwater chlorinators. It also fits other above-ground equipment that shares the same inlet/outlet thread and hose diameters.

• Compatible with many Intex filter pumps and chlorinator pump combos.
• Works with Intex model references such as 28635EG, 28633EG and related filter pumps.
• If your pool uses the same sized connections, the kit is likely to fit; contact us for confirmation.

Who is this for? Pool owners who want an easy, reliable way to shut off flow during maintenance or to upgrade their filtration pump without replacing hoses will find this kit especially useful. It’s geared to do-it-yourselfers maintaining Intex-compatible above-ground pools, service technicians who need spare parts on hand, and anyone upgrading from smaller pumps to higher-GPH systems. The package includes two plunger valves, two O-rings, two step washers and two 10722/25009 hose adapters so you can convert both sides of your plumbing and reduce downtime during summer pool care.
