SIGHT-PIPES® for Visual Inspection

Borescopes fabricated from optical grade materials that allow for difficult to inspect characteristics to be viewed.

-Regular Series SIGHT-PIPE®

Regular series SIGHT-PIPES® are used to visually inspect a specific portion of a machined bore or cavity for a particular characteristic. The SIGHT-PIPE® projects an image, of the piece part sidewall, to the top of the enlarged head of the SIGHT-PIPE® at a right angle (90°). The image seen would be similar to that produced by sectioning (cutting) the piece part and looking directly at the sidewall. Regular series SIGHT-PIPES® are available in standard diameters from 0.125″ to 1.000″ with special sizes available upon request. SIGHT-PIPES® can be used alone or with the accessories described below.

SIGHT-PIPE® Accessories:

– Stop Collar: Used to set the depth that the SIGHT-PIPE® can be inserted into the piece part. Useful when inspecting a characteristic at a specific depth.

– Light Input Adapter: Fits on the head of the SIGHT-PIPE® and properly positions a light source to direct light down the SIGHT-PIPE® illuminating the area being viewed.

– 1310 Portable Illuminator: Portable battery operated light source. (2 AA batteries)
