Choosing the right tubular pipe for your plumbing project can be challenging, especially for beginners or do-it-yourselfers. With different types of tubular products on the market and Oatey offering various options, it can be overwhelming to determine the best one for your project. Consider material, cost, application, and size to ensure you select the best tubular pipe for your specific needs.
Below, we'll guide you in making an informed decision, including discussing the factors to consider when selecting the best tubular pipes for your plumbing projects and the different materials and use cases for each type of tubular product.
1. Material
Tubular plumbing products come in two materials: brass and plastic.
Brass tubular products are typically chrome-plated and offer aesthetic appeal, making them common in higher-end projects. Also, brass products are more durable and commonly used in commercial projects.
On the other hand, plastic tubular products (or polypropylene materials) are more affordable, easier to cut, and offer corrosion resistance.
When choosing between the two, consider your budget, durability needs, and aesthetic appeal. Factoring in the application is also crucial.
For instance, there are certain scenarios where brass is unsuitable, such as in science labs or some dentist's offices. The waste materials in these settings can be highly corrosive to metal, which could cause significant damage over time. In such cases, a plastic trap can be advantageous because plastic does not corrode and is generally unaffected by most chemicals.
Unlike PVC/ABS pipes, plastic tubular products (or polypropylene materials) cannot be assembled with solvent cements but require slip nuts and washers.
2. Cost and Pipe Thickness
Cost is always a crucial factor when selecting tubular products. Plastic tubular products are more affordable than their brass counterparts, making them a popular choice for do-it-yourselfers looking for cost-effective plumbing solutions.
Though pricier, brass products offer better durability and longevity, making them an excellent option for commercial or long-term plumbing projects.
Brass tubular items are offered in three different thicknesses, or “gauges.”
-
The 17-gauge is the thickest and is often referred to as commercial grade, typically used in heavy-duty applications.
-
The 20-gauge is a mid-range thickness, offering a balance between durability and cost-effectiveness.
-
Lastly, the 22-gauge, Oatey's thinnest option, is often referred to as "budget grade,” a cost-effective choice for less demanding applications.
On the other hand, all Oatey plastic tubular products are schedule 10 in thickness.
3. Application
When selecting the best tubular products, consider the application. Oatey offers a variety of tubular products, including P-Traps, S-Traps, Wall Bends, Extension Tubes and more, all designed for specific applications.
Here are some examples of tubular applications and the appropriate tubular product for each. Oatey Tubular products are available in both brass and plastic material:
-
P-Traps: Ideal for under-sink installations, P-Traps are designed to prevent sewer gases from escaping into your home. They are most commonly used in bathroom and kitchen sinks. Read our blog title, What is a P-Trap and How Does it Work, for a closer look at P-Traps.
-
S-Traps: S-Traps are similar to P-Traps but are no longer approved for installations and are primarily in older homes and buildings.
-
Wall Tubes: These are pieces of pipe with a curve that fits under the sink and connects the P-Trap to the house's sanitary system. Wall Tubes are connected to the J-Bend to form the P-Trap and direct wastewater from the sink drain to the waste line without leaks.
-
Extension Tubes: These extend the waste pipe to the wall or floor. Extension Tubes come in various lengths and can be cut to size, offering flexibility for accommodating different installation needs.
-
Double Slip Joint Offsets: Double Slip Joint Offsets are essential for creating a seamless connection between two pipes at different heights or angles. They come in handy when you need to navigate around obstacles during a plumbing installation.
-
Branch Tailpieces: Branch Tailpieces are used to connect a dishwasher discharge hose to the sanitary system, making them ideal for dual-basin or single bowl kitchen sinks that do not have a garbage disposal.
-
End Outlet Continuous Waste: Ideal for dual-basin kitchen sinks.
-
Center Outlet Continuous Waste: Used when the drain is centered under a dual-basin sink.
-
Direct Connect Waste: Offers a direct connection to the sinks basket strainer.
-
J-Bends: Helps to form the P-Trap under the sink.
-
Captured Nuts and Washers: Made of durable polypropylene, these are used to secure your plumbing fixtures.
4. Size
The size of the tubular product you choose is equally important. Tubular pipes are available in various diameters, and the size you select should be compatible with your plumbing fixtures.
When selecting tubular products, it is important to consider the most common sizes, which are 1-¼ inch and 1-½ inch. These sizes are available in both brass and plastic materials.
The largest size of tubular product that can be connected with a slip nut and washer is determined by the trap adapter connection to the branch drain in the wall. Additionally, for 1-¼-inch tubular assemblies, the connection point can be reduced using a reducing washer and slip nut.
Typically, bathroom sink installations use 1-¼-inch products, although 1-½-inch products are also suitable. On the other hand, kitchen sink installations require 1-½-inch products exclusively.
Other Considerations
Considering corrosion resistance and insulating tubular pipes is essential for efficiency. Galvanized and stainless steel piping are not commonly used for tubular products, so only use them if your project demands it. Thread tapes and pipe joint compounds may also be used on the fine threads of a pop-up tailpiece to prevent leakage.
Oatey offers covers for ADA sink installations, including center/end outlet waste covers and P-trap covers.
Please note that the specific type of tubular product you will need depends on the requirements of your plumbing project. Be sure to understand these requirements before making a purchase. Always consult local building regulations and professionals as required.
Beyond the primary tubular products, Oatey also offers a wide range of tubular accessories to complement and enhance your plumbing projects. Some examples of these accessories include Slip Joint Nuts and Washers, Flanges, Air Gaps, and multiple Garbage Disposal Accessories.
Selecting the right tubular pipe for your plumbing projects requires careful consideration to determine which product will meet your needs and is budget-friendly, durable, and efficiently sized. Consider the material, cost, application, size, and other factors to avoid incompatible installations that may result in leaks and other damages.
Whatever your plumbing needs, selecting the right tubular product is critical for a successful plumbing project.
