30° Lift Angle

180° Pivot

360° Swivel

Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque Wrenches are sold separately.

Machined hoist rings have a smooth finish to protect slings and hooks from damage and excess wear during lifting.

Black-oxide steel offers mild corrosion resistance.

Nickel-coated steel is more corrosion resistant than black-oxide steel.

316 stainless steel provides the most corrosion resistance.

Hoist rings that are CE marked meet European requirements for health, safety, and environmental protection.

Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.

Warning: Never use to lift people or items over people.

Side-Mount Hoist Rings—For Lifting

Choose these hoist rings when you need to lift your load from the side. Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque Wrenches are sold separately.

Warning: Never use to lift people or items over people.

Rotating Eyebolts—For Lifting

Eyebolt

Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.

Powder-coated steel eyebolts are impact resistant, but less corrosion resistant than stainless steel eyebolts. They include a removable key for tightening the bolt.

Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.

Warning: Never use to lift people or items over people.

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air

Metric and UN/UNF
(SAE Straight) Male
Threads with Gasket

For Use With: Air, Lubricated Air
Temperature Range: 0° to 140° F, except plugs and straight connectors are 32° to 140° F
Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.

Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.

Metric and UN/UNF (SAE Straight) male threads with gasket or thread sealant provide extra protection against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
