Black plastic ball socket end fitting for gas spring – Ø10 mm ball – M6 – EFBS004P

Description of the plastic ball socket end fitting EFBS004P – Ø10 mm ball – M6 thread

The EFBS004P plastic ball socket end fitting is a spare part for gas springs (also called gas struts or gas lifts) made by SPEC / Associated Spring Raymond. It screws onto the M6 thread at the end of a gas spring, on either the rod or the cylinder body, and fits over a 10 mm diameter ball stud. This connection lets the gas spring pivot freely as a hatch, locker lid or panel opens and closes.

The black moulded plastic socket has a quick-release clip system. The top cap is marked OPEN and LOCK: in the open position the internal spring fingers let the socket slip over the ball, and in the lock position it is held firmly in place. You can disconnect a gas spring in seconds to reach a locker, swap a strut or service a hinge, with no tools and no loose parts to drop in the bilge.

The fitting has an 18 mm offset between the thread axis and the ball socket. It works with the stainless steel ball brackets used aboard pleasure craft and with any other mounting that has a 10 mm ball stud. It fits every gas spring with an M6 threaded end, so you can replace a broken or worn socket without changing the whole strut.

This is the simple, reliable and economical version. It works best inside the boat (cabin furniture, saloon lockers, bed bases, interior hatches) or in areas protected from direct sunlight. Exterior fittings on cockpit lockers, deck hatches, engine hatches or swim platforms face strong UV exposure, so for those we recommend the stainless steel alternative, EFBS002S.

The EFBS004P is sold individually and is also available in kits of 2 or 4 pieces, so you can refit one strut or the whole vessel at once.

Installation / Maintenance

Installation:

• Before taking off the old fitting, support the hatch or panel so the gas spring is not under load.
• Unscrew the damaged end fitting, then screw the EFBS004P fully onto the M6 thread of the rod or body.
• Turn the cap to OPEN, push the socket onto the 10 mm ball stud, then turn it to LOCK.
• Make sure the socket pivots freely on the ball and does not touch the bracket or surrounding structure through the full opening travel.

Maintenance:

• From time to time, check that the clip stays in the LOCK position and that the socket has no play on the ball.
• A light film of silicone grease on the ball stud reduces wear and keeps the joint quiet.
• Replace the fitting if the plastic is cracked, brittle or discoloured. Do not use solvents to clean it.
