What the 226-14091-4 Is
The Lincoln 226-14091-4 is the reinforced high-pressure member of the Quicklinc valve-body family. It is an aftermarket replacement part built for Quicklub high-pressure grease systems. Distributor catalogs list this family as push-in fittings, with designation RVV 6511-6-M for the M10 x 1 version. Suffix codes vary by catalog revision, so confirm the complete designation when ordering.
How the Reinforced Push-In Connection Works
The -4 uses a wider clamping-ring collar that locks onto a 6 mm hose stud with groove. Push the grooved stud into the collar until it seats, and the clamping ring holds it under pressure. To release, press the collar toward the body and pull the stud out. A built-in check valve prevents backflow through the connection when system pressure drops.
The 226-14091 Family
| 226-14091-2 | Standard version, narrower collar, bare 6 mm plastic pressure tubing, standard-pressure secondary lines |
| 226-14091-4 | Reinforced version, wider clamping-ring collar, 6 mm hose studs with groove, 350 bar class |

Compatible Hose Studs
The -4 accepts 6 mm hose studs with groove. Old catalog lists include these cross-reference numbers: 432-24162-1 short straight, 432-23067-1 long straight, 532-30739-1 90 degree short, and 532-30738-1 90 degree long. Confirm the shape your routing needs before ordering. The 432-24162-1 short straight hose stud and 532-30739-1 90 degree hose stud pages show two common options.
Installation Notes
The M10 x 1 male thread screws into the outlet port of a metering device, typically SSV or SSVD class secondary metering devices and lubrication points. Tighten with hand tools without forcing; excessive torque can crack a brass body. Confirm the specified torque in the current catalog. Sealing of the M10 x 1 port follows the port design of the metering device, so follow the device manual for the correct sealing method.

Can I push bare plastic tubing into the -4?
No, the reinforced collar is made for hose studs with groove. Use the -2 for bare 6 mm plastic tubing.
What pressure is the -4 rated for?
It serves Quicklub systems up to 350 bar (5,076 psi). The rating applies to the complete reinforced arrangement.
What thread does it screw into?
M10 x 1 male thread into the outlet port of the metering device. Follow the device manual for sealing.
What torque should I use?
The current catalog value governs; confirm it when ordering. Tighten with hand tools without forcing, because the brass body can crack.

6 mm hose studs with groove, including 432-24162-1, 432-23067-1, 532-30739-1, and 532-30738-1. Confirm the shape your routing needs.
Does it include a check valve?
Yes, a built-in check valve blocks backflow through the connection. This protects the metered line when pressure drops.
What is the body made of?
Nickel-plated brass is the listed construction. Confirm the finish on your order code.
Is there an elbow version?
Yes, the 226-14091-8 is the 90 degree reinforced version for grooved studs. It serves the same 350 bar class.
