Designed as an alternative to the usual steel worm drive type of hose clip, with uprated clamping performance, and far superior appearance.
Prolock clamps are a new product designed to provide a superior appearance in any engine bay to the usual hose clips. At the same time providing a high level of security, having been tested under road and track use for thousands of miles.
Prolock hose clamps are machined from high grade aluminium and are designed principally for all turbocharger system pipes and with the ability to hold over 4.0 BAR (60 PSA) boost pressure if required.
A range of sizes are available to suit most applications.
Prolock clamps are normally supplied with semi or highly polished finish, in a boxed set of 4 clamps, but can be supplied as a set to suit a particular vehicle.
Pro-lock clamps have a smaller range of adjustment than standard hose clips, so accurate measurement of the outside diameter of the turbo hose when it is actually fitted onto the pipework is required.
All Pro-lock sizes refer to the inside diameter of the clamp in an unadjusted condition, as taken out of the box.
Clamp Hose Pipe
AMC 60mm i/d 60mm o/d 51mm o/d
AMC 67mm i/d 67mm o/d 57mm o/d
AMC 73.5mm i/d 73.5mm o/d 63mm o/d
Typically, the outside diameter of a 3-pIy silicone hose increases in outside diameter by 1.5-2.5mm when put onto the pipe.

Prolock clamps have a unique locking mechanism which allows the allen bolt clamping screw to be screwed out to open up the clamp, to ease the fitting, and then to be locked in this position with a small grub screw until the clamp is in position on the hose, when the grub screw can be loosened and the clamp tightened.
It is essential that the clamp is not over tightened. Maximum torque of only :10lb.in. or KN is required to hold upto 4.0 BAR (60 psi).
