Dyme technical

1. Preparation: Confirm hose/fitting belong to the same family and size. Clean bench and components.
2. Square cut: Make a clean, straight cut; deburr lightly to minimize debris.
3. Nut setup (LH on some models): Thread the compression nut onto the hose using its internal thread until it bottoms.
4. Witness mark: Mark hose at the nut entry to watch for push-out during assembly.
5. Lubricate & seat: Lightly lube fitting nipple/threads; assemble until fully seated (target ≤1 mm final gap).
6. Verify: If push-out exceeds the mark, rework (trim and reassemble).
7. Flush & test: Clean to application standard; pressure-test prior to service.

Replace rubber hoses on a proactive cadence based on duty (e.g., ~5 years is a common baseline). For long-life race duty, PTFE families are preferred.

• Tooling: Use your approved crimper, die set, and collars for the family/size.
• Materials: Only use matched hose, collars, and fitting families.
• Validation: Record lot/batch, crimp diameters, and pressure-test results.

SUPERLEGGERA (PTFE) Lightweight, high-temp, broad chemical compatibility — ideal for pro racing and long-life duty.

SUPERSTRASSE (CPE) Robust street/track option — service-friendly; plan periodic renewals per duty/chemistry.

SUPERLEGGERA — Crimp Data

SUPERSTRASSE — Crimp Data

Use approved dies/collars and pressure-test assemblies. Rubber systems require proactive renewal based on duty/chemistry.

For methanol/nitromethane systems, pair with PTFE hose and verify fitting/seal family. Do not use FKM seals with brake fluid.

DYME METHODEX™ SEALS ARE SPECIALLY DESIGNED TO RESIST HIGHLY /CORROSIVE FUELS LIKE METHANOL AND NITROMETHANE, WITH A SPECIALLY FORMULATED GREY EPDM MATERIAL, WE RECOMMEND A MAXIMUM TEMPERATURE OF 160C/320F, THESE ARE AVAILABLE AS STANDARD IN THE HM-TYPE PRO/SPEC™ FITTINGS. WE DO NOT RECOMMEND USING THESE SEALS FOR ANY OTHER FLUID THAN THE ONES PRESCRIBED FOR ANY EXTENDED USE. MADE IN GERMANY.

DYME DYMAX™ FFKM PERFORMS IN THE HARSHEST RACING ENVIRONMENTS IMAGINABLE, AT HIGH TEMPERATURES WITH CORROSIVE FUELS AND CHEMICALS, WE RECOMMEND A MAXIMUM TEMPERATURE OF 310C/590F, THESE ARE AVAILABLE AS STANDARD IN THE SPECIAL ORDER HX-TYPE PRO/SPEC™ FITTINGS. DYMAX-F™ IS A FUEL AND FLUIDS SPECIALIST, WITH BROAD RESISTANCE OF GASOLINE TO NITROMETHANE, DYMAX-B™ IS A HIGH TEMPERATURE BRAKE SPECIALIST, EXTREMELY RESISTANT TO BRAKE FLUID AND EXTREME TEMPERATURES, FOUND IN DYME EX-TYPE BRAKING COMPONENTS. MADE IN ITALY.

DYME EPYROX™ PERFORM IN DYME’S BRAKE SYSTEM COMPONENTS, TYPICALLY USED IN E-TYPE, F-TYPE AND G-TYPE DRY BREAKS, RESISTANT TO LONG TERM EXPOSURE TO ALL TYPES OF DOT BRAKE FLUID, AND RESISTANT TO CONSISTENT TEMPERATURES OF 160C/320F, EPYROX™ IS A STABLE LONG LASTING PART OF YOUR BRAKE SYSTEM. MADE IN GERMANY.

DYME FLUOROX™ IS OUR ALL ROUNDER SEAL MATERIAL WITH FKM BASE FORMULATION, THIS SEAL TYPE HAS THE BROADEST RESISTANCE TO ALL COMMON FUELS LIKE GASOLINE, DIESEL AND ETHANOL (E85), AS WELL AS OILS FOR ENGINES, TRANSMISSIONS AND GEAR SETS. FLUOROX™ HAS EXCELLENT LONGEVITY AND RELIABILITY AT TEMPERATURES UP TO 205C/401F. THIS MATERIAL IS NOT COMPATIBLE WITH BRAKE FLUID OF ANY TYPE. MADE IN GERMANY.

Legend: ○ = compatible, X = not compatible. * Check series-specific notes. ** Rubber systems may require proactive renewal based on duty/chemistry. *** Use appropriate non-swivel fittings only.

* FOR PROFESSIONAL RACING WITH ADVANCED FUELS SUCH AS ETHANOL E100, 100 OCTANE, C16 ETC. WE RECOMMEND ALWAYS USING PTFE HOSES AS THEY HAVE THE WIDEST AND BEST COMPATIBILITY OVER TIME AND IS A CRITICAL SAFETY MEASURE.

METHANOL IS ONLY CURRENTLY SUPPORTED BY FATBOY H-TYPE (NON-SWIVEL) DUE TO THE CORROSIVNESS OF THE FUEL, PRO/SPEC H-TYPE WILL SUPPORT IT IN THE FUTURE WITH FFKM SEAL UPGRADE. USE WITH PTFE HOSE.

NITROMETHANE IS ONLY SUPPORTED BY FATBOY H-TYPE (NON-SWIVEL) DUE TO THE CORROSIVNESS OF THE FUEL, PRO/SPEC H-TYPE WILL SUPPORT IT IN THE FUTURE WITH NBR SEAL UPGRADE. USE WITH PTFE HOSE.

** E85 IS HARMFUL TO RUBBER IN VEHICLE SYSTEMS OVER TIME, TO COUNTERACT THIS DYME RUBBER HOSES LIKE SUPERSTRASSE INCLUDES A CPE LINER THAT PROTECTS THE RUBBER SUBSTRATE FROM ATTACK. OVER TIME THIS LINER CAN BE DEGRADED DEPENDING ON THE FREQUENCY OF USE, HEAT, DAMAGE AND OTHER CONDITIONS. IN GENERAL WE RECOMMEND CHANGING THE HOSE MATERIAL AT LEAST EVERY 5 YEARS AS A PREVENTATIVE MEASURE, AND FOR RACING PURPOSES MORE FREQUENTLY, TO BE DETERMINED BY THE SITUATION. E85 CAN ALSO MIGRATE INTO THE MOTOR OIL OF THE CAR AND AFFECT OIL HOSES OVER TIME, PLEASE BEAR THESE FACTORS IN MIND WHEN SELECTING A HOSE MATERIAL, AND IF IN DOUBT, ALWAYS SELECT A PTFE SOLUTION. 

*** BRAKE FLUID IS NOT COMPATIBLE WITH ANY FITTING OR ADAPTER THAT HAS AN FKM (VITON (R)) SEAL, PLEASE USE NON SWIVEL TYPES OF FITTINGS AND A COMPATIBLE PTFE HOSE.
