1/2 inch x 3/8 inch PVC Reducing Adapter Male x Insert (Pack of 2)

701-012 Nylon Adapter – 1/2 inch MPT x 3/8 inch Barb – For Poly Tubing and Threaded Transitions

The 701-012 Nylon Adapter from DiversiTech is a precision-molded fitting designed to facilitate a secure transition between a 1/2 inch male pipe thread (MPT) and a 3/8 inch barbed connection. Constructed from durable, high-grade nylon, this adapter is suitable for use in fluid transfer systems, condensate drainage lines, irrigation setups, and other non-potable applications.

The combination of barbed and threaded ends allows for flexible integration into hybrid piping assemblies where tubing and rigid pipe must interface. Nylon construction offers chemical resistance, dimensional stability, and excellent performance in ambient and low-pressure environments.

Performance Characteristics

• ✅ Injection-Molded Nylon – Provides strength and resistance to deformation under moderate thermal and mechanical stress.
• ✅ Dual-End Configuration – Threaded MPT end for rigid pipe or manifold connections, with a barbed outlet for 3/8 inch ID flexible tubing.
• ✅ Corrosion and Chemical Resistance – Compatible with a variety of non-corrosive liquids and environmental conditions.
• ✅ Reduced Permeability – Maintains seal integrity under intermittent flow and moderate backpressure scenarios.

Specifications

• Material: Glass-filled or high-density nylon (depending on batch spec)
• Thread Size: 1/2 inch MPT (Male Pipe Thread – NPT compatible)
• Barb Size: 3/8 inch OD hose/tube barb
• Operating Conditions: Suitable for low to moderate pressure systems (verify per application)

Installation Recommendations

Install with compatible thread sealant or PTFE tape to ensure a watertight seal at the MPT connection. Use stainless steel hose clamps at the barbed end to secure flexible tubing. Avoid overtightening to prevent cracking or thread damage. This fitting is not intended for pressurized potable water systems or high-temperature service without manufacturer approval.

Common Applications

Frequently used in HVAC condensate drain lines, irrigation risers, water filtration systems, and equipment assemblies requiring flexible-to-threaded transitions. Applicable in utility closets, mechanical rooms, and field installations where space constraints or material compatibility demand non-metallic fittings.

Material Note

Nylon is favored for its lightweight, non-conductive properties, and its performance in moisture-rich or chemically mild environments. Its dimensional consistency supports tight engagement with pipe threads and tubing without the need for specialized tooling.

The 701-012 Nylon Adapter provides a durable, corrosion-resistant transition for contractors working across drainage, irrigation, and low-pressure system applications. It delivers mechanical reliability and installation flexibility where metal fittings are either not required or not preferred.
