Do You Supply Custom PTFE Gaskets by Drawing or Sample?
Yes — Dalian Luyang supplies custom PTFE gaskets, seals, and related parts either from your drawing (OEM) or from a physical sample, with a clear, straightforward process. Whether you send a 2D/3D drawing, a CAD file, or a physical sample to reverse-engineer, our PTFE capability (LY-401/403/405 grade families) is backed by ISO 9001 and ISO 13485 quality management. This article explains exactly how OEM/ODM custom PTFE gasket supply works, and what to prepare to get the fastest, most accurate quote.
1. The Two Ways to Engage: OEM and ODM
| Mode | What it means | Best when |
|---|---|---|
| --- | --- | --- |
| OEM | We produce to your drawing and specification | You have a defined design, brand, and compliance needs |
| ODM | We design / develop the part (with you), often from a sample or concept | You have a part or rough idea but need engineering input |
Many projects start OEM from a drawing and evolve to ODM when we help optimise geometry, grade, or tolerances. Both routes are supported.
2. The Two Ways to Provide the Part
You can start with either:
- By drawing — send a 2D drawing (PDF/DWG/DXF), 3D model (STEP/IGES), or a detailed spec with dimensions, tolerances, material, and quantity. We quote from the geometry.
- By sample — send a physical PTFE gasket or seal; we reverse-engineer dimensions and material, quote for an identical or improved part.
Provide whichever is fastest for you — if you have a working part but no complete drawing, reverse-engineering from a sample is often quicker than redrawing.
3. What to Prepare for a Faster Quote
To get an accurate quote faster, include:
| Item | Why it matters |
|---|---|
| --- | --- |
| Drawing (2D/3D CAD) | Defines geometry and tolerances |
| Dimensions / size range | For quotation |
| Material / grade (e.g. PTFE LY-401/403/405) | Sets properties & price |
| Quantity and frequency | Volume pricing |
| Tolerance / critical features | Cost and lead time |
| Application (hydrogen, food, medical...) | Compliance & grade fit |
| Target price / deadline (optional) | Scope alignment |
| Sample (if no drawing) | Reverse-engineering input |
The more complete your input, the fewer clarification rounds — and the faster we can quote.
4. Typical Quotation Timeline
Transparent and realistic timelines help you plan:
| Step | Typical duration |
|---|---|
| --- | --- |
| Drawing/sample received & reviewed | 1–2 business days |
| Technical clarification (if any) | 1–3 business days |
| Quote issued | Within ~3–5 business days of complete info |
| Tooling/setup (custom) | Depending on complexity |
| Production & QC | Per order size / schedule |
For a standard review with complete information, you can generally expect a quotation within a few business days. Complex or tooled parts take longer — we communicate clearly.
5. PTFE Gasket Capability: Grades & Features
Our PTFE program (LY-401/403/405) supports a wide variety of sealing parts:
- Custom-cut gaskets, seals, O-rings, and profiles
- Electrolyser cell gaskets (built for hydrogen/electrolysis sealing duty)
- Virgin PTFE for highest chemical purity
- Complex cut, punched, and machined geometries
- Custom sizes, thicknesses, contours, and bolt-hole patterns
PTFE's key sealing advantages — low friction (typically ~0.05–0.10), chemical inertness, and a continuous temperature range around 260 °C (short-term up to 327 °C crystalline melt) — are leveraged in gaskets across chemical, food, and hydrogen applications.
6. Quality and Documentation
With every custom PTFE order you can expect:
- ISO 9001 (and ISO 13485 for medical-related) quality management
- Material datasheet for the exact grade with test methods
- Certificate of Conformity
- Dimensional inspection report on critical features on request
- Traceability records from material lot to finished part
If your gasket needs to meet food-contact or other regulatory requirements, confirm your application category and we will scope the applicable evidence.
7. Getting Started
To request a custom PTFE gasket quote:
- Send your drawing (STEP/DWG/DXF/PDF) or a physical sample by email.
- Include material preference, quantity, tolerance, and application notes if known.
- Receive our technical review and quotation.
- Approve sample (if applicable), then production under a clear schedule.

Send your drawing or physical part, include grade/quantity/application, and get a transparent technical review and quote within a short turnaround. Dalian Luyang (www.newmaterialchina.com), established 2006, brings decades of PTFE, PEEK, and PI precision-part experience to your sealing program.
Frequently Asked Questions
- Can you make a PTFE gasket from a physical sample? Yes — we reverse-engineer dimensions and material from a sample and can quote for an identical or improved part when no drawing exists.
- What should I send for a custom gasket quote? Ideally a 2D/3D drawing (STEP/DWG/DXF/PDF) with material, quantity, and tolerances; if you have no drawing, a physical sample is sufficient to start.
- How long does a custom PTFE gasket quote take? With complete information, expect a technical review and quote within about 3–5 business days; complex or tooled parts may take longer.
