Metal & X-ray detectable seals for food processing
Food and beverage equipment needs food-contact compliant materials, and many plants also require seals that metal and X-ray detectors can find. We supply custom CNC-machined detectable seals in four FDA grades, made by our specialist production partner.
4 detectable gradesPU, FKM, EPDM and PTFE

4 detectable grades
Pick the base material for your conditions
All 4 grades are FDA grades and are designed to be found by metal and X-ray detectors. Choose by temperature, cleaning medium and the fluid being sealed.
Metal & X-ray detectable FKM
80 Shore A · -30 / +200 °C · Blue
FDADETECTABLE
High temperatures and many chemicals, with low gas permeability.
Quote this grade →Metal & X-ray detectable EPDM
80 Shore A · -50 / +135 °C · Blue
FDADETECTABLE
Hot water, steam and many acids and alkalis: the preferred choice for food and beverage equipment. Low resistance to oils.
Quote this grade →Metal & X-ray detectable PTFE
60 Shore D · -200 / +260 °C · Blue
FDADETECTABLE
Acids, bases, alcohols and fuels, with low friction for high speeds. Not elastic, so usually paired with an energizer.

FAQ
Common questions
Which detectable materials do you offer?
Four base materials: Metal & X-ray detectable PU (BP-PU95-06, 95 Shore A, -20 to +90 °C); Metal & X-ray detectable FKM (BP-FK80-01, 80 Shore A, -30 to +200 °C); Metal & X-ray detectable EPDM (BP-EP80-01, 80 Shore A, -50 to +135 °C); Metal & X-ray detectable PTFE (BP-PT-37, 60 Shore D, -200 to +260 °C). All four are FDA grades.
Which grade handles hot water and steam cleaning?
EPDM is the rubber for hot water and steam (BP-EP80-01, up to +135 °C). For higher temperatures, FKM (BP-FK80-01, up to +200 °C) and PTFE (BP-PT-37, up to +260 °C) are options. Tell us your cleaning process and we'll recommend one.
Can you replace our existing seals with detectable versions?
Yes. Send a drawing or a sample and the operating conditions, and we'll quote the detectable equivalent.
What is the minimum order?
It depends on the seal, but it's usually around 20 pieces. Tell us what you need and we'll confirm the minimum in your quote. Seals are CNC-machined from billet stock, so there's no mould or tooling cost.
Can you make a replacement from a worn seal?
Yes. Register your sample, we'll email you the shipping address in California or New York, and we'll measure, identify and quote it.
