TonGass Trimline Ball Valve 2-Pack — 1.5" MIP x 1.5" FIP, All-ABS Non-Corrosive, 50 psi

The TonGass 2-pack 1.5" MIP x 1.5" FIP Trimline ball valve is an all-ABS, non-corrosive two-way valve designed to replace Hayward SP0723-style union fittings for easy skimmer, pump, and filter connections.

This pair of trimline ball valves lets you control water flow between 1.5" male and female plumbing connections without metal parts that corrode. Built from ABS plastic, each valve includes a union end for fast disconnection, a replaceable stem and O-rings, and a secure handle for quarter-turn operation. With a maximum working pressure of 50 psi, these valves are intended for residential pool and spa equipment where compatibility with 1.5" Hayward-style fittings is required.

How does this valve fit with existing 1.5" pool plumbing?

The TonGass valve is made to mate directly with common 1.5" male and female pipe adapters used on skimmers, pumps, and filters. One end is 1.5" male iron pipe (MIP) and the other is 1.5" female iron pipe (FIP), matching the same dimensions as the Hayward SP0723-style union assembly for quick swaps.

• 1.5" MIP connects to female inlet/outlets on filters and pumps.
• 1.5" FIP accepts 1.5" male hose adapters or fittings.
• Union nut enables hand-tightened disconnection during maintenance.
• Suitable as an aftermarket direct replacement for SP0723-style unions.

What materials and durability features does the valve have?

Every component of this valve is molded from ABS plastic, including the stem and ball, eliminating metal corrosion and reducing the chance of a seized stem. ABS offers UV resistance and long-term durability in outdoor pool environments, and several internal parts can be serviced if wear occurs.

• All-ABS construction resists rust and UV degradation.
• Replaceable stem, O-rings, ball, handle, and end connectors.
• Plastic union nuts allow tool-free loosening in tight spaces.

What are the pressure and performance limits I should know?

This trimline ball valve is rated to a maximum of 50 psi and is intended for domestic pool and spa circulation systems that do not exceed that pressure. It provides reliable on/off flow control and a compact profile for installations where space is limited.

• Maximum working pressure: 50 psi — do not exceed.
• Two-way ball valve design for straightforward shutoff and flow control.
• Quarter-turn handle for fast open/close operation and visual flow position.

How do I choose the correct variation for my application?

Hayward-style union fittings may come with different end types (FIP, SKT, MIP), so pick the variation that matches the mating part in your system. This TonGass listing replaces the SP0723-style FIP variant; if your system uses a socket (SP0723S) or another union end, select the matching configuration.

• Confirm whether your existing union uses FIP, SKT, or MIP ends before ordering.
• TonGass SP0723-style replacement corresponds to the FIP union connector variant.
• Contact support or check the original part number if uncertain about fitment.

Who is this for: Pool and spa owners, service technicians, and DIYers who need a corrosion-resistant replacement for Hayward-style 1.5" union valves. It’s ideal when you want a lightweight, UV-resistant plastic valve with serviceable internals and easy union disassembly for skimmer and pump maintenance.
