Pipe Insert Adapter 1-1/4" MIP Nylon White - Boshart Industries UNA-12 (3-PACK) The Boshart Industries UNA-12 1-1/4-inch nylon insert adapter is a lead-free, high-performance fitting designed to transition from 1-1/4-inch polyethylene (PE) tubing to standard 1-1/4-inch male pipe thread (MPT) connections. Constructed from durable, UV-stabilized nylon, it provides a reliable, corrosion-resistant interface between flexible PE water lines and rigid threaded piping systems ? ideal for irrigation, potable water, and low-pressure distribution applications. The insert end slides securely into the PE tubing, while the MPT threaded end screws directly into female NPT fittings such as valves, pumps, or faucets. Designed for pressures up to 200 psi, it ensures a secure, leak-free connection when used with Teflon thread tape on the threaded joint. Features - Nylon construction resists corrosion, UV degradation, and chemical exposure - Insert-style inlet accepts 1-1/4 in PE tubing for tool-free, compression-free installation - 1-1/4 in MPT outlet threads directly into standard female NPT fittings - Rated for 200 psi maximum operating pressure ? suitable for high-pressure irrigation and water systems - Lead-free formulation complies with federal Safe Drinking Water Act requirements - White finish blends with standard PE and PVC plumbing components - Teflon thread tape recommended for optimal seal on threaded connections - Lightweight at 0.09 lb ? easy to handle and install in tight or remote locations - Compatible with HDPE, MDPE, and other standard polyethylene tubing per ASTM F714 - Designed for cold water applications only ? not rated for hot water or steam - Bagged for clean, organized delivery and job-site storage - No gluing, crimping, or heat fusion required ? simplifies field installations Specifications - Brand Name: Boshart Industries - Model Name: Boshart Industries UNA-12 - Product Type: Insert Adapter - Material: Nylon - Color: White - Inlet Type: Insert (for PE Tubing) - Inlet Diameter: 1-1/4 in - Outlet Type: Male Pipe Thread (MPT) - Outlet Diameter: 1-1/4 in - Thread Type: NPT (National Pipe Taper) - Maximum Pressure: 200 psi - Temperature Rating: Cold Water Only (Typical Use: Ambient to 140F) - Certification: Lead-Free - Weight: 0.09 lb - Quantity: 1 pc per pack - Packaging: Bagged - Country of Origin: United States - UPC: 777808130481 - GTIN: 00777808130481 - Alternative UPCs: 048643165441, 098268038927, 739236435514 - Nomenclature: UNA-12 NYLN INSRT ADAPT1.25MIP - Manufacturer: Garmel Holding Inc. Product Application The Boshart Industries UNA-12 nylon insert adapter is used by irrigation contractors, plumbers, and agricultural installers connecting flexible polyethylene water lines to rigid threaded components such as shut-off valves, pump outlets, sprinkler risers, or faucet adapters. Ideal for drip irrigation systems, residential water service lines, and landscape water features, it enables quick, reliable transitions without the need for expensive fusion tools or mechanical fittings. Its high-pressure rating and chemical resistance make it suitable for both municipal and private water systems ? delivering the quiet confidence of a durable, code-compliant connection that withstands daily use and environmental stress.
