PTFE Lined Reducer
Model:PTFE Lined Reducer
We can perform Lining in Eccentric Reducer as well as Concentric Reducer. We are one of the renowned names in providing PTFE Lined Reducer to our clients. We manufacture these products as per the industry norms.
Kaxite PTFE Lined Reducer is a flanged pipe fitting lined with virgin PTFE, PFA, or FEP to deliver outstanding corrosion resistance in aggressive chemical service. Available in concentric and eccentric configurations, the PTFE Lined Reducer provides a smooth, non-stick, chemically inert flow path for pipe size transitions. The carbon steel or stainless steel housing carries the mechanical load, while the fluoropolymer liner isolates the media from the metal surface. Manufactured in compliance with ASTM F1545, these reducers are ideal for chemical, pharmaceutical, and petrochemical plants. Request a quote →
PTFE Lined Reducer – Reliable Corrosion Protection for Pipe Size Transitions
Kaxite PTFE Lined Reducer is a precision-engineered flanged pipe fitting designed to handle highly corrosive fluids without compromising structural integrity. The steel outer shell carries the mechanical load, while the internal PTFE liner isolates the transported media from the metal surface, preventing corrosion, contamination, and product build-up. This makes the reducer an ideal choice for pipe size transitions in chemical dosing systems, transfer lines, and process connections.
Our PTFE Lined Reducers are available in both concentric and eccentric configurations to suit different pipeline layouts and drainage requirements. The liner is available in PTFE, PFA, and FEP to match various temperature and purity requirements. Standard lining thickness is 3 mm, and custom thicknesses can be supplied on request. All reducers are manufactured in accordance with ASTM F1545, with fixed or loose flanges as per client specification. Contact our engineering team for custom sizes, reduction ratios, and flange drilling.
Key Features & Benefits
- ✅ Excellent Chemical Resistance – PTFE, PFA, and FEP liners resist virtually all acids, bases, solvents, and oxidizing agents.
- ✅ Concentric & Eccentric Options – Available in both configurations to suit drainage, venting, and layout requirements.
- ✅ Temperature Resistant – Continuous service from -29°C to +260°C, depending on the liner material selected.
- ✅ Anti-Corrosive Construction – Steel shell provides pressure containment; the liner protects against media attack.
- ✅ Excellent Surface Finish – Smooth liner surface minimizes friction loss and prevents material accumulation at the transition.
- ✅ Long Service Life – Combines structural strength with outstanding chemical durability.
- ✅ Flexible Liner Options – PTFE, PFA, or FEP available to match your process media and temperature.
- ✅ Flange Flexibility – Fixed or loose flanges, drilled to ANSI, DIN, JIS, or custom standards.

Liner Material Selection Guide
Choose the optimal liner material based on your chemical media, operating temperature, and purity requirements.
| Liner Material | Max. Temperature | Chemical Resistance | Typical Applications |
|---|---|---|---|
| PTFE | 260°C | Excellent against most chemicals | General chemical processing, acids, bases |
| PFA | 260°C | Similar to PTFE, better flexibility | High-purity applications, semiconductor |
| FEP | 200°C | Good chemical resistance | Food & beverage, pharmaceutical |
* Liner selection should consider permeation, thermal cycling, and vacuum service. Contact Kaxite for a detailed recommendation.

Frequently Asked Questions
- Q: What types of PTFE Lined Reducers do you offer?
- A: We offer both Eccentric Reducers and Concentric Reducers, and PTFE lining can be performed in either configuration. Custom reduction ratios are also available.
- Q: What is the difference between a concentric and an eccentric reducer?
- A: A concentric reducer reduces the pipe diameter symmetrically about the centerline and is used in vertical pipelines. An eccentric reducer keeps one side flat, which is preferred for horizontal lines to prevent liquid pooling or vapor pocketing.
- Q: What is the standard lining thickness of a PTFE Lined Reducer?
- A: The standard thickness of PTFE lining is 3 mm. However, we can perform lining of higher thickness on demand to suit specific pressure or permeation requirements.
- Q: Can the reducer be supplied with loose flanges?
- A: Yes, we can provide reducers with fixed or loose flanges as per the client's requirement. Flanges can be drilled to ANSI, DIN, JIS, or custom standards.
- Q: Do you offer PFA and FEP liners as alternatives to PTFE?
- A: Yes, lining can be done using PFA and FEP materials as well. These offer similar chemical resistance with improved flexibility or purity for specific applications.
