Description

Westlake Pipe & Fittings 1435-015 Female Adapter, 1.5″ Insert x FPT

The Westlake Pipe & Fittings 1435-015 Female Adapter, 1.5″ Insert x FPT, is a durable, high-performance connector engineered to transition seamlessly from flexible hose to threaded plumbing components. This precision-made fitting is widely used in pool and spa plumbing, irrigation systems, water circulation setups, pond installations, and general-purpose fluid movement applications. With its insert-style barb on one end and a strong female threaded (FPT) connection on the other, it allows installers to join flexible 1.5-inch tubing directly to pumps, filters, valves, manifolds, unions, and various PVC fittings with reliability and long-term stability.

Constructed from premium, corrosion-resistant polymer, the Westlake 1435-015 is designed to withstand constant exposure to moisture, soil conditions, chlorinated pool water, and fluctuating temperatures. Unlike metal fittings that may degrade or fittings made from low-quality plastics that can crack under pressure, this adapter retains its structural integrity for years. Its chemical resistance makes it an excellent choice for water systems containing sanitizers, algaecides, or other treatment agents, ensuring that the connection remains secure and leak-free over time.

A key advantage of this adapter is its versatile design. The 1.5-inch insert side features a multi-barb configuration that grips flexible hose firmly when installed with a standard stainless-steel clamp. These barbs create a powerful mechanical hold, reducing the chance of disconnection even under pressure surges or continuous pump operation. The texture and spacing of the barbs are engineered to maximize hose contact, enhancing friction and sealing performance while maintaining easy installation.

On the opposite side, the female threaded end allows the adapter to connect directly to male threaded components with a tight, standardized fit. This versatility makes the 1435-015 a crucial adapter when connecting flexible plumbing lines to rigid PVC systems or equipment with threaded ports. Whether you’re attaching a hose to a pool pump intake, connecting spa plumbing to a heater, or incorporating flexible lines into a manifold, the female thread provides a strong and reliable interface.

Installers appreciate how quick and simple the installation process is. No primer or PVC glue is required. The insert end is pushed into flexible hose and secured with clamps, while the threaded end attaches using thread tape or pipe sealant to ensure a watertight connection. This makes the adapter ideal for repair work, system upgrades, and situations where easy disassembly is preferred. Because the connection is mechanical rather than solvent-welded, the fitting can be removed and reused if system layouts change in the future.
