per EACH (USD)Cushioned P-Clamp, 1/2" (12.7 mm) ID, Black
Holds a hose, line, tube or wiring bundle of 1/2" (12.7 mm) outside diameter against a bracket or panel.
The Racetronix CPC-8 is a P-clamp with a black 5052 aluminum band and an EPDM rubber cushion. Wrap it round the hose or line, bolt the two tabs to a bracket or panel, and the cushion grips it firmly while damping vibration and protecting the surface.
Key features
- Inside diameter: 1/2" (12.7 mm). Sized to the clamp, not to the hose's AN size.
- EPDM rubber cushion lining the band.
- 5052 aluminum band, black.
- Mounting tab at each end with a hole for a bolt or screw (not included).
- The EPDM lining grips without crushing, damps vibration and protects hoses, lines and finished parts.
- Neat, low-profile mounting for fuel, brake and oil lines, hose and wiring.
Choosing the size
Measure the outside diameter of the hose, line, tube or part you want to hold, and choose the clamp with the same inside diameter. If you are between sizes, choose the next size up: the rubber cushion takes up a small gap, and a clamp that is too small will not close.
Typical uses: securing fuel and brake lines, hoses and wiring bundles, and mounting round components such as in-line fuel filters and external pumps.
How to install
- Wrap the clamp round the hose, line or part.
- Line up the two bolt tabs and fit a bolt through both into your bracket or panel.
- Tighten until the part is held firmly without being crushed.

Frequently asked questions
Which size do I need?
Measure the outside diameter of the hose, line or part and choose the clamp with the same inside diameter. Between sizes, choose the nearest one; the rubber lining takes up small differences.
What is the difference between this and a hose clamp?
A hose clamp seals a hose onto a barb. A P-clamp holds a hose, line or part in place and mounts it to something, with a rubber cushion to stop rubbing and vibration.
