Pack of ten zinc-plated steel grease fittings with 90-degree angled heads

Westward

Westward 52NZ75 Grease Fitting 90 Deg Steel 1/2" PK10

SKU CH-BCDW-KD6FX

Pack of ten 90-degree steel grease fittings with 1/8-inch PTF threads and 1 to 5 psi relief pressure

  • Pressure-relief valve protects bearings
  • 1–5 psi cracking range prevents over-lubrication
  • 1/8"-27 PTF threads fit standard ports
  • Zinc-plated steel resists corrosion
  • Pack of 10 fittings covers multiple jobs

Pressure-Relief Grease Fittings

This pack contains ten Westward 52NZ75 steel fittings with a zinc-plated finish. Each unit features a 90-degree head angle and a 1/2-inch overall length. They use a 1/8-inch PTF thread with a 27-thread pitch. The internal valve opens between one and five psi to relieve excess pressure.

Mechanics Servicing Tight-Angle Points

The 90-degree head suits maintenance on equipment where straight access is blocked by frames or guards. Technicians who need a straight-head fitting or a different thread standard should select another style. The fixed relief range cannot be adjusted for systems requiring a higher cracking pressure.

Ten-Pack Coverage for Fleet Top-Ups

Ten pieces cover multiple lubrication points across a small fleet or a single heavy machine. The low-pressure relief valve protects seals during routine grease-gun top-ups. The valve will not protect components if system pressure spikes far exceed the five-psi maximum.

Highlights

  • Pressure-relief valve protects bearings
  • 1–5 psi cracking range prevents over-lubrication
  • 1/8"-27 PTF threads fit standard ports
  • Zinc-plated steel resists corrosion

Questions about this item

What thread size must my grease gun or port have to accept these 1/8 in.-27 PTF fittings?

The fittings use a 1/8 in.-27 PTF thread; the mating port or gun must match that exact thread specification for a proper seal.

Will the 90° head angle and 1/2 in. overall length clear the same tight spots as the straight fittings I currently use?

The 90° head redirects flow perpendicular to the thread axis and the 1/2 in. length keeps the profile low, so it fits where straight fittings cannot.

How can I verify the pressure-relief function is working after installation?

Apply grease until the fitting vents; the relief activates between 1 and 5 psi, so you should see excess grease escape at very low pressure.
