About Gas Springs

Gas springs are typically used to assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Gas Springs

These general purpose gas springs assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Long-Life Gas Spring Style Mechanical Springs

Mechanical operation means these springs have no seals to fail or gas to leak.

Corrosion-Resistant Gas Springs

Stainless steel construction provides corrosion resistance for use in damp environments.

Corrosion-Resistant Long-Life Gas
Spring Style Mechanical Springs

With no gas to leak out and a corrosion-resistant 316 stainless steel construction, these mechanical springs are built for long-term, maintenance-free use in wet environments.

High-Temperature Gas Springs

A temperature-resistant seal allows these gas springs to withstand heat up to 392°F.

Add-a-Fitting Gas Springs

These gas springs have threaded ends so you can use them with any combination of end fittings, studs, and mounting brackets.

Corrosion-Resistant Add-a-Fitting Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Miniature Gas Springs

Miniature Gas Springs with Eyelet Fittings

Sized with short stroke lengths and miniature dimensions, these gas springs are for opening small lids and doors, like those on toolboxes and access panels.

High-Force Miniature Gas Springs

Small in size, but not in strength, these gas springs are often used to replace coil springs in metal stamping and die-spring applications.

Color-Coded High-Force Miniature Gas Springs

Color coded by force to help you choose the correct replacement, these gas springs generate high force in small spaces.

Corrosion-Resistant Miniature
Gas Springs with Eyelet Fittings

Made from stainless steel for excellent corrosion resistance in damp environments.

Reducible-Force Gas Springs

Corrosion-Resistant Reducible-Force
Gas Springs with Eyelet Fittings

Made from stainless steel for excellent corrosion resistance in damp environments. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Reducible-Force Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Locking Gas Springs

Corrosion-Resistant Locking Gas Springs

Automatically locking when fully extended and made of 316 stainless steel to resist corrosion, these gas springs protect material and equipment underneath heavy loads in damp environments.

Locking Gas Springs

Protect material and equipment underneath heavy loads—these gas springs lock automatically when fully extended, ensuring they can't be closed until it's safe to do so.

Reducible-Force Locking Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Reducible-Force
Locking Gas Springs

Release gas from these springs until they supply the exact force you need—made of corrosion-resistant 316 stainless steel, they’re commonly used in wet environments.

Remote-Release Gas Springs

Pair one of these gas springs with a release control to stop and release the gas spring anywhere along the stroke with the push of a button or lever.

Pulling Gas Springs

Also known as tension and traction gas springs, these work in the opposite direction of other gas springs. Similar to a screen door closing, they're used to assist in closing covers, hoods, and doors.

Eyelet Mounting Brackets for Gas Springs

Attach eyelet end fittings to these brackets to mount gas springs.

Corrosion-Resistant Eyelet
Mounting Brackets for Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Corrosion-Resistant Heavy Duty Eyelet
Mounting Brackets for Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Heavy Duty Eyelet Mounting Brackets for Gas Springs

These brackets secure eyelet end fittings from both sides to provide a strong hold on gas springs that get bumped or jostled. Mount on any panel, lid, or door.
