Can Collets type LDR, LD, LR, carbon steel fit hoses if I only know the hose internal diameter Dw and external diameter Dz?

Yes . Collets type LDR, LD, LR, carbon steel can be selected using only the hose internal diameter (Dw) and external diameter (Dz), because the sleeve selection is based on those two dimensions. How to choose: - Use Dw to check compatibility with the sleeve internal diameter D2. - Use Dz to check compatibility with the sleeve external diameter D1 and the locking diameter D3 where applicable. - Ensure the sleeve length L is equal to or slightly (a few mm) greater than the tail length Lk of the chosen end fitting. - Select type by end fitting: LD for corrugated-tail ends (NH-xxK-xxx), LR for ends intended for shell clamps (TW-KRS-xxx, NH-xxR-xxx), LDR when you need compatibility with both end types. - Note material: galvanized carbon steel . verify suitability for your application (corrosion, hygiene requirements). If you provide Dw and Dz (and optionally required end type and Lk), I can recommend specific D1/D2/D3 values and whether LDR/LD/LR is appropriate.

Do Collets type LDR, LD, LR, carbon steel require knowing both hose internal diameter Dw and external diameter Dz to select the correct sleeve?

Yes. For Collets type LDR, LD, LR, carbon steel you must know both the hose internal diameter (Dw / D2) and external diameter (Dz / D1) to select the correct sleeve. Selection depends on matching D2 to the hose bore and D1 to the hose outer size so the sleeve fits the tail and locks at the specified locking diameter D3. Also check sleeve length L versus tail length Lk (L may be a few mm longer). LDR fits both tail types, LD for corrugated tails, LR for shell-clamp tails.

Do Collets type LDR, LD, LR, carbon steel require both hose inner diameter Dw and outer diameter Dz to choose the correct sleeve?

Yes. to choose the correct sleeve for Collets type LDR, LD, LR, carbon steel you must consider both the hose inner diameter (Dw) and outer diameter (Dz). These sleeves are designed to clamp specific hygienic stainless steel ends (NH-xxK-xxx) and ends for shell clamps (e.g., TW-KRS-xxx, NH-xxR-xxx) used on industrial hoses. Selection uses: - Dw (internal diameter) to ensure the sleeve fits over the hose inner profile and mates correctly with the endâs tail. - Dz (external diameter) to match the sleeveâs internal diameter (D2) and the sleeveâs external diameter (D1), and to ensure proper locking diameter (D3) when clamped. Notes: - LR sleeves: only for ends under shell clamp. - LD sleeves: only for ends with corrugated tail. - LDR sleeves: for both types. - Sleeve length L should be slightly (a few mm) greater than the end tail length Lk. - Material: galvanized carbon steel. Therefore both Dw and Dz are required to select the correct sleeve dimensions (D1, D2, D3) for secure clamping.

Additional information

Material	CS – steel (cast iron)

LDR, LD, LR type sleeves are designed for clamping hygienic stainless steel ends (with a corrugated tail) type NH-xxK-xxx and ends with a tail for hose under a shell clamp RS, e.g., TW-KRS-xxx, NH-xxR-xxx in industrial hoses (rubber and plastic with textile reinforcement, possibly with a reinforcing spiral – suction and pressure hoses). The sleeve should be selected considering the internal diameter Dw and external diameter Dz of the hose. The length of the sleeve L may be slightly (a few mm) greater than the length of the tail of the end Lk. LR sleeves – only for ends under the shell clamp, LD – only for ends with a corrugated tail, LDR – sleeves for both types of ends. Diameter D1 [mm] – external diameter. Diameter D2 [mm] – internal diameter. Diameter D3 [mm] – locking diameter. Material: galvanized carbon steel.
