Compact Regulator Diaphragm 114X46

The SPEEDAIRE 114X46 is a replacement diaphragm built for compact air regulators. It restores pressure control on compatible units used in automotive workshops and general pneumatic systems.

Direct replacement for listed Grainger parts

Installation consists of removing the regulator bonnet, swapping the old diaphragm and reseating the spring. The part fits Grainger numbers 1WH33, 4ZK82 through 4ZK85 and 4ZM14 through 4ZM17. Misalignment during reassembly is the most common cause of leaks.

Maintains regulation under continuous cycling

The diaphragm material resists fatigue from repeated pressure swings in shop compressors. It delivers consistent actuation during extended duty cycles rather than only during brief test bursts. Compatible with Speedaire branded regulators.

Questions about this item

How can I confirm the SPEEDAIRE 114X46 diaphragm is regulating pressure correctly after installation?

Observe the regulator gauge while the compressor runs; the needle should hold steady at the set pressure without creeping up or dropping when air is drawn.

What comes with the SPEEDAIRE 114X46 compact regulator diaphragm and is any extra hardware required?

The package contains the diaphragm only; mounting screws, seals or a replacement regulator body are not included and must be sourced separately if yours are worn.

Which SPEEDAIRE part numbers does the 114X46 diaphragm fit so I choose the right one?

It is compatible with Grainger part numbers 1WH33, 4ZK82, 4ZK83, 4ZK84, 4ZK85, 4ZM14, 4ZM15, 4ZM16 and 4ZM17.
