Why Plastic Lined Piping Accessories Matter
Plastic lined piping accessories aren’t just add-ons—they’re essential components that help optimize performance, extend service life, and maintain safety. With durable steel cores protected with a coating of PTFE or other high-performance linings, these accessories ensure that even in aggressive or highly corrosive environments, your system remains leak-free and efficient.
From controlling flow to providing expansion flexibility, lined accessories make installations easier, reduce long-term maintenance, and protect valuable equipment. The result is a piping system that works reliably under pressure, delivering peace of mind to engineers, operators, and project managers alike.

Plastic-Lined Pipe Accessories Available from Marspec
Large Diameter Lined Pipe
When your system calls for higher volume and bigger flows, large diameter lined pipe is the answer, combining the structural strength of steel with the corrosion resistance of PTFE linings. Our large-diameter lined pipe is built to handle challenging fluids in demanding industrial environments. Marspec offers lined pipe in a wide range of diameters, making it easier to design and install systems that can move more product without sacrificing protection against corrosion.
Solid PTFE Pipe
For applications that demand the highest levels of chemical resistance, solid PTFE pipe is often the preferred choice. Unlike steel-lined options, solid PTFE pipe is manufactured entirely from PTFE, eliminating any potential for permeation or corrosion at the core. This makes it ideal for handling ultra-pure or highly aggressive media where maintaining product integrity is critical.
Fittings and Valves
No piping system is complete without fittings and valves that match the same level of performance as the pipe itself. Marspec carries a full range of plastic lined fittings and valves, each designed to provide reliable service in corrosive conditions. Whether you need elbows, tees, reducers, or lined ball and plug valves, our catalog covers everything required to keep your system flexible, secure, and ready for operation.
Strainers
Strainers play an important role in protecting sensitive downstream equipment by filtering out debris and unwanted solids. Plastic lined strainers combine the durability of a robust housing with a chemically resistant lining, ensuring effective performance even when handling corrosive fluids. This not only extends equipment life but also helps maintain consistent flow and system efficiency.
Sight Flow Indicators
When you need to monitor what’s moving through your system, sight flow indicators provide a clear visual check. Lined with PTFE for resistance to aggressive media, these accessories are essential for applications where confirming flow direction, rate, or quality is part of routine operations.
PTFE Expansion Joints
Thermal expansion, vibration, and system movement are realities in any piping system. PTFE expansion joints absorb these stresses, reducing strain on your pipe and minimizing the risk of leaks or failures. They’re lightweight, flexible, and resistant to a wide variety of chemicals, making them a go-to choice for demanding environments.
Solid and Armored PTFE Spacers
Spacers are essential for maintaining correct distances in a piping system and for accommodating dimensional variations during installation. Solid PTFE spacers provide excellent corrosion resistance, while armored PTFE spacers add an additional layer of durability for applications where mechanical strength is equally important.
Mixing Tees
Mixing tees are designed to combine multiple streams within a piping system efficiently. By lining these components with PTFE, Marspec ensures that mixing operations can be carried out without risk of corrosion or contamination. This makes them especially useful in chemical and pharmaceutical processes where precision and reliability are critical.
Spectacle Blinds
Spectacle blinds are a simple but highly effective way to isolate or block off sections of a piping system for maintenance or safety purposes. Plastic lined spectacle blinds combine strength with corrosion resistance, allowing operators to manage flow paths without compromising system integrity.
