Keystone Pinch Clamp - SAE Type "J"

Murray KEYSTONE pinch clamps offer superior strength.
KEYSTONE clamps are 100% stainless steel.

Keystone Pinch Clamps have a welded construction, are quick and easy to install, and provide a uniform, tamper proof seal. Keystone Pinch Clamps are widely used on both soft hose and rigid plastic pipe. You will find these clamps anywhere you connect poly pipe. Keystone Pinch Clamps are excellent for use in a multitude of irrigation and water supply systems, on fuel and vapor lines, to attach dust shields and air filters, for beverage supply lines, for car wash supply lines, and for securing bundles of cable. When crimping with a hand tool, Murray's true Keystone geometry, located in the ear area, dramatically reduces miscrimps. Keystone Pinch clamps are 100% Stainless Steel.

How to Determine Proper Clamp Size:

Measure actual Outside Diameter of hose on fitting, or overall O.D. of items to be clamped together. Select a clamp size whose clamping range includes this O.D.
