Standard Dimensions

Mechanical joint pipe is available in Special Thickness Class 53 only.

See Historical Data when retainer glands are being considered in lieu of regular glands.

When bell flanges tapped for studs are required, alloy steel stud bolts with the required stud length equal to the length of the tee head bolt it replaces should normally be specified.

Boltless Fastite, Fast-Grip, Flex-Ring and Lok-Ring push-on joint pipe and fittings are normally less labor-intensive and labor-reliant than mechanical joints pictured and are often preferred for many applications.
