Pipe Fitting Set Push In Bulkhead Fitting Plastic Thread Protector Rubber Gasket Gas Pipe Fitting

Product Description

Pipe Fitting Set Push-In Bulkhead Fitting Plastic Thread Protector Rubber Gasket Gas Pipe Fitting

Product Overview
This complete brass adapter fitting kit is a necessary pipeline conversion spare part for tankless gas and electric instant water heaters. Each set contains two solid brass female thread adapters, high-temperature rubber sealing gaskets and adjustable flow restrictors. The brass connectors act as a transition joint between the water heater and household water pipes, while the green flow limit inserts control inlet water flow to stabilize outlet water temperature. The matched rubber washers form tight sealing to stop water leakage at thread connections. Anti-corrosion brass material fits long-term hot water circulation environment, ideal for equipment maintenance and pipeline refitting.

Main Advantages
Heavy-Duty Brass Adapters
Pure copper integrated casting effectively resist rust and scale corrosion caused by hot water, far more durable than plastic or iron connectors.

Adjustable Water Flow Function
Install the green flow restrictor to reduce incoming water volume when water pressure is too high, avoid low outlet temperature; remove the restrictor for larger water flow output.

Zero Leakage Sealing System
High elasticity black rubber gaskets fill gaps between threads, prevent dripping water from pipe joints even under long-time hot water circulation.

Universal Compatibility
Standard G1/2 female thread perfectly fits the inlet and outlet ports of mainstream instant water heaters, direct replacement without thread modification.

All-in-One Pack Convenience
All required installation accessories are included in one package, convenient for after-sales maintenance merchants and household self-repair.

Installation Tips
Place the rubber gasket inside the brass adapter before screwing onto the water heater port.

Insert the green flow restrictor into the inner cavity of the brass fitting if you need to limit water flow.

Tighten the connector by hand moderately; do not over-tighten to avoid thread cracking.

Check joint leakage after installation by opening the water tap fully.
