4 Factors to Consider When Pairing UPVC Fittings with Pipes

Developing a plumbing system involves many considerations, mainly finding the right parts, such as pipe fittings and connectors. Since these components are key to joining and lengthening pipes or changing the direction of water flow, choosing the wrong fittings can lead to all sorts of issues. These can include unexpected downtime, corrosion, and even potential injuries.

Given the abundance of fitting types available, finding the right ones for a specific project can be tricky at times. Therefore, to ensure fixture compatibility and optimal functionality of the plumbing system, these three primary factors should be considered when selecting pipes and fittings:

1. Application

Although pipes and fittings are used interchangeably, the two are wholly different in how they are measured and their purpose. UPVC pipes, for example, find wide applications in drainage, sewage systems, venting, and non-pressure scenarios. On the other hand, UPVC pipes are predominantly utilised for fluid transfer in non-pressure applications.

Plumbing pipes typically fall into one of the following categories:

  • Fluid transport: These pipes efficiently transport fluids from one location to another. For example, SS141 UPVC pipes in Singapore are specifically designed for potable water, while SS272 UPVC pipes are designed for underground drainage, guaranteeing seamless flow and effective fluid management.
  • Electrical sheathing: Better known as electrical conduits, these pipes are designed to protect sensitive electrical wiring against various environmental hazards.
  • Structural applications: These are pipes/tubes with mechanical properties designed for use in buildings and structures.

2. Size and Dimensions

Pipe fittings have two thread types, male and female, found on both ends. Male threads are found on the outside of the pipe, while the female threads are located inside, the former screwing into the latter.

Alongside the threading, UPVC pipes and fittings are manufactured in a range of sizes, featuring diverse outer diameters and wall thicknesses. Selecting the correct size is vital, depending on the specific purpose of the system and its flow requirements. By choosing the appropriate size, you can ensure proper compatibility, optimal performance, and efficient fluid transfer within the system.

3. Standards and Certifications

In addition to considering the suitability of UPVC pipes for the intended application, verifying whether they meet the necessary standards and certifications is essential. In the case of our products, the SS141, SS272, and SS213 UPVC pipes are certified with Green Mark Certifications.

By choosing UPVC pipes with such certifications, you can have peace of mind knowing that they have met stringent quality and performance requirements. Moreover, certified pipes offer an added layer of safety assurance, ensuring the well-being of the system and its users.

4. Durability

UPVC pipes are highly regarded for their exceptional durability and ability to withstand environmental challenges such as corrosion, chemicals, and UV rays. Nevertheless, it is crucial to consider several factors that can impact the lifespan of these pipes.

The conditions during installation, maintenance practices employed, and exposure to extreme environmental conditions all play a significant role in determining the overall lifespan of UPVC pipes. To ensure their longevity and optimal performance, it is essential to prioritise proper installation techniques, implement regular maintenance routines, and protect the pipes from extreme conditions.



A plumbing system needs not only good pipes but also compatible fittings of equal quality. Being thorough when measuring ensures proper sizing and selection of these two components, enabling any plumbing system to perform properly and optimally.
