Custom Rubber Gaskets

Die-cut, waterjet and flashcut gaskets from your drawing. Any 2D profile in NBR, EPDM, silicone, neoprene, FKM or PTFE.

Overview

Custom rubber gaskets are made to your drawing, sample or flange specification. We cut 2D profiles from sheet stock using three main methods: steel-rule or punch die-cutting for cost-effective volume, waterjet cutting for prototypes and complex shapes without tooling, and CNC flashcutting for medium runs and tighter tolerances. To quote a custom cut rubber gasket, we need the drawing in DXF, PDF or STEP format, or a clear dimensional sketch with ID, OD, thickness, material, hardness and quantity. If the gasket replaces an existing part, send a photo or physical sample and we will reverse-engineer the dimensions. Cut method determines tolerance, lead time and unit cost. Die-cutting achieves the tightest tolerances (±0.1–0.2 mm) and lowest piece price but requires a tool, making it economical above roughly 500–1,000 pieces depending on size. Waterjet cutting has no tooling cost and is ideal for prototypes and small runs, with typical tolerances ±0.2–0.5 mm. Flashcutting bridges the gap: no hard tooling, better tolerance than waterjet (±0.1–0.3 mm), and competitive for medium volumes. Material options include NBR, EPDM, VMQ silicone, CR neoprene, FKM and PTFE in hardnesses from 30 to 90 Shore A. MOQ starts at one piece for prototypes. Standard lead time is 7–15 days for cut gaskets; expedited 3–5 day service is available for many materials.

Cut Methods

Method	Tolerance	Tooling	Best For
Die-Cut Gaskets	±0.1–0.2 mm	Yes	Volume production, simple to moderate profiles
Waterjet Gaskets	±0.2–0.5 mm	No	Prototypes, low volume, thick or soft materials
Flashcut Gaskets	±0.1–0.3 mm	No	Medium volume, foam and rubber sheet, intricate profiles

Frequently Asked Questions

What file format should I send for a custom rubber gasket?

DXF is preferred for 2D profiles. PDF drawings and STEP files are also accepted. If you only have a sample, send a photo with dimensions or mail the sample for reverse engineering.

What is the minimum order quantity for custom cut gaskets?

MOQ starts at one piece for waterjet or flashcut prototypes. Die-cutting requires a tool, so it becomes economical typically above 500–1,000 pieces depending on size.

What tolerance can you hold on a die cut gasket?

Die-cut gaskets typically hold ±0.1–0.2 mm. Waterjet is usually ±0.2–0.5 mm and flashcut is ±0.1–0.3 mm, depending on material and thickness.

Can you cut gaskets from customer-supplied material?

Usually we supply material to ensure traceability and quality. Contact us for cutting-only arrangements if you have approved material already in stock.

How do I choose between die-cut and waterjet gasket?

Choose die-cut for volume and tight tolerance. Choose waterjet for prototypes, low volume, thick materials or complex profiles without tooling cost.

Do you offer prototype custom gaskets?

Yes. We recommend waterjet or flashcut for prototype quantities starting at one piece, with lead times as short as 3–5 days.
