CONNECT 203-204
CONNECT 203-204 is a stainless steel adapter for metal hoses in the 375, 376 and 377 series. The construction is offered in two variants: 203 has a cylindrical adapter with one-sided expansion for hose insertion; 204 has the same cylindrical base construction but with a slot that allows crimping or attachment via clamp. 13 dimensions with ID range from 40 mm to 300 mm cover the full metal hose catalogue's main range. Typically used in fixed-installation applications where permanent attachment of the metal hose to process facilities, ventilation or high-temperature transport is prioritised over quick disassembly.
- Stainless INOX

Frequently asked questions
What is the difference between 203 and 204?
Both are stainless INOX adapters with the same base geometry. CONNECT 203 has a cylindrical adapter with one-sided expansion - the hose is inserted and typically fastened via clamp on the expansion. CONNECT 204 has the same cylindrical geometry but is slotted - i.e. there is a slot/opening along the adapter that allows crimping, joining or specific fastening solution.
Which one to choose for what?
Choose CONNECT 203 for standard fixed-installation where a clamp over the expansion is sufficient. Choose CONNECT 204 if the project requires a slotted construction to join two hose ends, or where a specific fastening mechanism (crimping tool, ferrule) must handle the slot structure.
Which hoses?
CONNECT 203-204 is qualified for our full metal hose catalogue: METAL HOSE 375 (PUR-coated), 375 HT (high-temperature), 376 INOX (stainless steel) and 377 REINFORCED (aluminium-reinforced). 13 dimensions from ID 40 mm to 300 mm match the hose catalogue's dimension range.
Are 203 and 204 sold separately?
Yes. Each variant and dimension has its own article number (suffix 1100 for 203 base construction). For specific 204 slot variants or other material specifications, contact us.
