When two Faithfull hose clips cover the same diameter

If the outside diameter at the clip position is 38 mm, two Faithfull hose clips cover that number on paper. The manufacturer lists size 1X at 30–40 mm and size 1M at 32–45 mm. Once the ranges overlap, the measurement alone leaves the order reference open.

Read the overlap before choosing a size

• 31 mm falls within the nominal 30–40 mm range only, out of these two clips.
• 38 mm falls within both nominal ranges.
• 42 mm falls within the nominal 32–45 mm range only, out of these two clips.

These are examples of how to read the range. Actual suitability depends on the hose, fitting and application. Check the hose or equipment documentation for the clamp type and material specified for the connection.

Write down the information that resolves the choice

Record the outside diameter at the position where the clip is intended to sit, using the hose and fitting information for that connection. A hose’s advertised bore is an inside measurement. If the old clip has a legible size mark or part reference, record it separately. Note any specified clip material and any space restriction around the band or screw housing.

Here is a sample order note you can fill in before contacting the merchant. “Outside diameter at clip position: ___ mm. Existing clip mark or part reference: ___. Hose and fitting reference: ___. Required clip type and material: ___. Clearance to check: ___.” When both catalogue ranges cover the measurement, use the remaining details to confirm which reference to order.

Match the catalogue reference at checkout

Faithfull lists FAIHC1XB as size 1X, nominal 30–40 mm, and FAIHC1MB as size 1M, nominal 32–45 mm, in its zinc-plated mild-steel range. Faithfull lists stainless-steel variants separately. If the application specifies stainless steel, confirm that reference before ordering.
