Which Accessories Are Compatible with Your Air-Jet Valve Model?

Key Takeaway: Accessories follow the valve bore diameter: ø8mm → Type A, ø10mm → Type B, ø12mm → Type C, ø16mm → Type D. Never mix types — seal dimensions are not interchangeable.

Valve Model	Bore ø	Seal Kit	Air Fitting	Spacer	Extraction Tool
AJV-08	ø8mm	SK-A	PF-6-1/8	SP-08	ET-08
AJV-10	ø10mm	SK-B	PF-6-1/8	SP-10	ET-10
AJV-12	ø12mm	SK-C	PF-8-1/4	SP-12	ET-12

Ordering Tips

Seal kits (10-pack): 15% discount on bulk orders. Recommended for shops maintaining 10+ molds.
Extraction tools: One tool per valve size is sufficient — it works for all valves of that diameter regardless of length.
Spacers: Model-specific. Used to adjust valve seat depth when the bore is deeper than the valve body length.

Frequently Asked Questions

Can I use generic O-rings instead of manufacturer seal kits?+

Generic O-rings can be used if they match the exact dimensions (ID, cross-section) and material (Viton FKM or Kalrez FFKM). The poppet seal, however, is valve-specific and must be sourced from the valve manufacturer.

Are extraction tools necessary?+

Not strictly necessary — valves can be removed with soft-jaw pliers. However, extraction tools are designed to grip the valve body without damaging the sealing surfaces, reducing the risk of bore damage. Recommended for frequent maintenance.
