3/4 inch x 3/8 inch PVC Reducing Adapter Male x Insert (Pack of 2)

701-043 Nylon Adapter – 3/4 inch MPT x 3/8 inch Barb Transition Fitting

The 701-043 Nylon Adapter is a precision-molded fitting engineered to provide a secure transition between a 3/4 inch male pipe thread (MPT) and a 3/8 inch barbed connection. Commonly used in irrigation, condensate drainage, and low-pressure fluid systems, this adapter offers chemical resistance, structural stability, and ease of integration for professional applications.

Manufactured from high-grade nylon, this component is lightweight, durable, and suitable for use in environments exposed to water, non-corrosive chemicals, and fluctuating temperatures. Its two-mode connection configuration makes it suitable for hybrid piping systems involving flexible tubing and threaded rigid lines.

Professional-Grade Features

• ✅ Dual Connection Design 3/4 inch MPT to 3/8 inch barb for quick adaptation between pipe threads and flexible tubing.
• ✅ Corrosion-Resistant Nylon Offers long-term performance in wet or humid environments without rust or degradation.
• ✅ Lightweight & Non-Conductive Ideal for electrical isolation or use in systems sensitive to metal contact.
• ✅ Precision Molded Threads Ensure a tight mechanical seal with standard PTFE tape or approved sealant.

Technical Specifications

• Material: Injection-molded nylon
• Size: 3/4 inch MPT x 3/8 inch Barb
• Configuration: Male threaded end to barbed hose connection
• Temperature Range: Suitable for typical cold and ambient fluid applications
• Use Category: Low-pressure systems (not for potable hot water or high-pressure fluids)

Installation Notes

Apply PTFE thread sealant to the MPT side for optimal leak resistance. Push the 3/8 inch tubing fully over the barbed section and secure with a stainless steel hose clamp if pressure containment or vibration resistance is required. Ensure alignment is free of kinks or torque to maintain joint stability.

Common Applications

This adapter is frequently used in HVAC condensate lines, irrigation control systems, water filtration units, and chemical feed lines. Its hybrid configuration supports installations involving both rigid and flexible tubing components within utility systems.

Material Insight

Nylon is valued for its dimensional stability, UV resistance, and low moisture absorption, making it suitable for both indoor mechanical rooms and outdoor distribution setups. Its non-metallic properties help prevent galvanic interaction when used adjacent to copper or brass systems.

The 701-043 Nylon Adapter delivers reliable performance in hybrid pipe assemblies and auxiliary plumbing systems. Its durable construction and dual-interface design support efficient installations and long-term reliability in field service environments.
