Lasco® Fittings Schedule 40 Threaded Reducer Bushing — 3/4in × 1/2in

Lasco® Schedule 40 PVC Threaded Reducer Bushing — 3/4in × 1/2in

The Lasco® 3/4-inch × 1/2-inch Schedule 40 PVC Threaded Reducer Bushing transitions between two different NPT pipe sizes — 3/4-inch male thread on the larger end inserts into a 3/4-inch FPT fitting, while the 1/2-inch female thread accepts a 1/2-inch male NPT fitting or pipe nipple. This concentric reducer is used throughout cold water irrigation manifolds and hydroponic plumbing wherever supply lines or headers transition to smaller distribution branches or accessory connections.

Key Features & Benefits

• 3/4in MPT × 1/2in FPT Configuration — Reduces from 3/4-inch to 1/2-inch NPT in a single compact fitting for clean, tight transitions.
• Schedule 40 PVC — Pressure-rated for standard cold water irrigation and hydroponic system requirements.
• All-Threaded Assembly — No solvent cement required; installs and removes with standard pipe wrenches for easy system reconfiguration.
• Corrosion-Resistant — Unaffected by fertilizer salts, pH chemicals, and sanitizing solutions in recirculating hydroponic systems.
• Cold Water Rated — Designed for cold water service consistent with typical hydroponic and irrigation operating temperatures.

Who Should Use This

Hydroponic plumbers and greenhouse irrigation installers use threaded reducer bushings wherever supply manifolds transition to smaller branch lines, inline strainers, or component inlets — providing a convenient, removable size transition without cutting or re-cementing pipe.

Compatibility

3/4-inch MPT end threads into standard 3/4-inch FPT fittings. 1/2-inch FPT end accepts standard 1/2-inch MPT nipples, valves, and fittings. Cold water use only. Apply PTFE thread tape to all threads before assembly.

Frequently Asked Questions

Do I need thread sealant on this bushing?

Yes — apply PTFE thread tape or PVC-compatible pipe thread compound to the male threads before installation to achieve a leak-free seal.

Can I use this bushing in Schedule 80 fittings?

The NPT thread form is the same for Schedule 40 and 80 fittings. This bushing will thread into 3/4-inch NPT Schedule 80 female fittings without issue.

Is this bushing removable for system changes?

Yes — threaded fittings can be removed and reused. Apply fresh thread tape on reassembly to maintain a leak-free seal.

What is the maximum working pressure for this bushing?

Schedule 40 PVC threaded fittings carry a pressure rating dependent on temperature. Consult Lasco's published pressure-temperature charts for the exact rating at your operating conditions.
