CMP 25550-004-000 Pool In/Out Fitting, 1.5″ FIP, Vinyl, Black
The CMP 25550-004-000 Pool In/Out Fitting, 1.5″ FIP, Vinyl is a precision-engineered pool wall fitting designed to provide reliable water circulation for vinyl liner swimming pools. Manufactured by Custom Molded Products (CMP), a trusted name in pool and spa components, this in/out fitting is built to ensure consistent performance, watertight integrity, and long-term durability in residential and commercial pool systems. Designed specifically for vinyl liner applications, it serves as a critical connection point between the pool’s interior and the plumbing system behind the wall, enabling efficient water intake and return flow essential for filtration, heating, and sanitation.
Constructed from high-quality, corrosion-resistant materials, the CMP 25550-004-000 fitting withstands continuous exposure to chemically treated pool water, UV rays, and varying environmental conditions. The black finish not only offers a sleek, unobtrusive appearance that blends seamlessly with darker pool interiors and fittings, but also resists fading and discoloration over time. Its durable body is engineered to maintain structural integrity under pressure fluctuations commonly experienced in circulation systems, ensuring leak-free operation throughout the swimming season and beyond.
This fitting features a 1.5-inch FIP (Female Iron Pipe) threaded connection, making it compatible with standard 1.5-inch MIP plumbing components widely used in pool installations. The threaded design allows for a secure, tight seal when properly installed with thread sealant or Teflon tape, reducing the risk of leaks and simplifying both initial setup and future maintenance. Its versatile configuration allows it to function as either an inlet or outlet fitting, depending on the plumbing layout and specific circulation requirements of the pool system.
Designed with vinyl liner pools in mind, the CMP 25550-004-000 incorporates a secure wall-mounting assembly that compresses the liner between the fitting body and faceplate to create a watertight seal. This helps prevent water seepage behind the liner, which can lead to structural damage, liner floating, or costly repairs. The precision-molded construction ensures uniform dimensions and consistent fitment, minimizing installation challenges and ensuring professional results whether installed by a contractor or experienced DIY pool owner.
Water circulation is one of the most important factors in maintaining clean and healthy pool water. This in/out fitting plays a central role in distributing filtered and treated water evenly throughout the pool. Proper placement and installation of return fittings like this one help eliminate dead spots, improve chemical distribution, and enhance overall water clarity. When used in conjunction with high-performance pumps, filters, and sanitation systems, the CMP fitting contributes to balanced water chemistry and improved swimmer comfort.
The robust internal threading and reinforced body construction allow the fitting to handle typical residential pool operating pressures without cracking or warping. Unlike lower-grade plastic fittings that may degrade over time, CMP’s manufacturing standards emphasize long-term reliability. The material composition is resistant to pool chemicals such as chlorine and bromine, as well as saltwater systems, making it suitable for a wide range of pool sanitization methods. This adaptability ensures that the fitting remains dependable regardless of the pool’s treatment system.
Installation efficiency is another key advantage of this model. The straightforward threaded connection reduces installation time and provides flexibility for plumbing adjustments. The fitting integrates seamlessly with standard return jets, directional eyeballs, and other compatible pool wall accessories, allowing pool owners to customize water flow direction and velocity. This adaptability supports improved circulation patterns and can even enhance heating efficiency by optimizing warm water distribution.
Aesthetically, the black finish offers a modern, understated look that complements contemporary pool designs. Dark fittings are particularly popular in pools with darker liners or natural-style finishes, as they remain visually subtle and do not distract from the overall pool appearance. Beyond aesthetics, the UV-resistant properties help maintain color stability, ensuring that the fitting retains its clean, professional look season after season.
