Westward Button Head Coupler 5/8 6000 psi

This Westward button head coupler is a new component designed for lubrication systems. It connects to a 5/8 inch button head grease fitting to deliver fluid under pressure. Maintenance technicians and machine shop operators use it to service equipment requiring high-pressure grease delivery. The part is built from steel, zinc, Buna-N and nylon for durability.

Rated 6000 psi with Buna-N Nylon Steel Zinc

The coupler withstands a working pressure of 6000 psi during normal lubrication tasks. Its wetted materials include Buna-N, nylon, steel and zinc, which resist deformation and wear under load. No abnormal noise or thermal concerns are associated with this passive mechanical fitting. Power draw is not applicable as the device operates without electrical input.

Fits 5/8 inch button head grease fittings only

This coupler fits 5/8 inch button head grease fittings exclusively and will not connect to other fitting sizes or thread types. Compatible series, brand and manufacturer model numbers are not applicable, so buyers must verify the fitting dimensions on their equipment. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. It is restricted from sale in certain states.

Questions about this item

How do I install the Westward button head coupler on a 5/8 in grease fitting without cross-threading?

Align the coupler squarely with the 5/8 in button head grease fitting and thread it on by hand until the Buna-N, Nylon, Steel and Zinc wetted materials seat fully; the step people get wrong is forcing it with a wrench before the threads engage.

What maintenance will the Westward button head coupler need after repeated greasing jobs?

Wipe the Buna-N, Nylon, Steel and Zinc wetted surfaces clean after each use and inspect the seal for cracks or deformation; replace the coupler if the internal check mechanism no longer holds 6000 psi pressure.

What limit appears first when the Westward button head coupler is used continuously at high pressure?

The 6000 psi pressure rating is the first limit reached under sustained use; exceeding it can damage the Buna-N, Nylon, Steel and Zinc wetted components and cause leaks.
