Parker to AirTAC cylinder cross-reference (ISO 15552)
The verified equivalents for Parker P1F profile cylinders — with the spec differences shown, not hidden.
Parker’s P1F ISO 15552 cylinders cross-reference to AirTAC’s SAI series. Both declare conformance to ISO 15552, so for a given bore they share the mounting interface and the rod-end thread — the mount is a drop-in. Order the AirTAC with a G (BSPP) port to match Parker. The pressure ceiling is identical at 10 bar; only the floor rises, from 1 to 1.5 bar. Watch two things the standard does not cover: the AirTAC is rated to 70 °Cagainst Parker’s 80 °C, and its piston rod is carbon steelwhere Parker’s standard is stainless. No seal change is needed. Overall verdict: equivalent-with-changes.
Before you cross-reference: the Parker side has moved. Parker lists the standard-profile P1D as obsolete; the current series is the P1F, covering the same Ø32–125 mm ISO 15552 range. If the cylinder you run today is a P1D, the AirTAC SAI below is the equivalent for it too — but a like-for-like Parker replacement means a P1F, not another P1D.

| Spec | Parker | AirTAC | Difference |
|---|---|---|---|
| Bore | 32 mm | 32 mm | match |
| Stroke | 100 mm | 100 mm | match |
| Mounting | ISO 15552 | ISO 15552 | shared mount |
| Rod-end thread | M10 × 1.25 | M10 × 1.25 | match |
| Port thread | G 1/8 (BSPP) | 1/8 — G optional | order G to match |
| Seal | Polyurethane | TPU | same class — no change |
| Operating pressure | 1–10 bar | 1.5–10 bar | same ceiling; 0.5 bar higher floor |
| Max temperature | 80 °C | 70 °C | lower — Viton for higher |
| Piston rod | Stainless steel (standard) | Carbon steel | call out if corrosion-exposed |
Before you substitute: Same ISO 15552 mount and rod-end thread — interchangeable on the mounting. Order the AirTAC SAI with a G (BSPP) port to match Parker. Unlike the Festo swap, the pressure ceiling is identical at 10 bar; only the floor rises, from 1 bar to 1.5 bar, so check any circuit that actuates below 1.5 bar. No seal change is needed — Parker ships polyurethane and the AirTAC ships TPU, the same class. Two things to watch: Parker's standard build is rated to 80 °C against the AirTAC's 70 °C, and Parker's standard piston rod is stainless steel where the AirTAC's is carbon steel — call the rod material out explicitly if the cylinder sits in a wet or corrosive location.

What matches, and what to set when you order
ISO 15552 fixes the mounting dimensions and the rod-end thread for each bore, so a Parker P1F and an AirTAC SAI of the same bore are interchangeable on the mount. The differences sit in what the standard leaves to the manufacturer:
- Port thread.Parker’s European order code fixes G (BSPP) per bore. Order the AirTAC SAI with the G option so the port matches — see port threads: G (BSPP) vs NPT.
- Pressure floor only.Both top out at 10 bar. The AirTAC needs 1.5 bar to move against Parker’s 1 bar, so the only exposure is a circuit that actuates below 1.5 bar.
- Temperature.Parker’s standard build is rated to 80 °C, the AirTAC to 70 °C. Between those two figures you lose margin; specify Viton (FKM) on the AirTAC if you need it.
- Piston rod material — the one you cannot order around. Parker’s standard rod is austenitic stainless steel; the AirTAC’s is carbon steel. Every other difference on this page is an option you tick when ordering. This one is a build difference, so if the cylinder sits in washdown or a corrosive atmosphere, raise it explicitly rather than assuming parity.
How this differs from a Festo swap
Worth knowing if you have read our Festo cross-reference: the Festo DSBC is wider than the AirTAC at both ends of the pressure range (about 0.4 to 12 bar against 1.5 to 10), so a Festo swap loses headroom at the top as well as the bottom. Parker does not repeat that pattern — the ceiling matches exactly and only the floor moves. Do not carry the Festo caution across to a Parker substitution; it overstates the risk.
As on every page, we do not publish a cycle-life figure for either series because neither manufacturer publishes one.
Frequently asked
Is AirTAC a drop-in replacement for Parker ISO 15552 cylinders?
On the mounting, yes. Parker's P1F and AirTAC's SAI both declare ISO 15552, so for a given bore they share the mounting interface and the rod-end thread. Overall it is an equivalent-with-changes: order the AirTAC with a G (BSPP) port, check that nothing in your circuit actuates below 1.5 bar, and note the AirTAC's 70 °C ceiling against Parker's 80 °C. No seal change is needed — both ship polyurethane.
Is the Parker P1D still current?
No. Parker's own product page for the standard-profile P1D is titled OBSOLETE, and the replacement is the P1F series, whose catalogue covers the same Ø32 to Ø125 mm ISO 15552 range. If you are cross-referencing from a P1D you already run, the Parker side has moved too — the P1F is the current Parker part, and the AirTAC SAI is the China-manufactured equivalent for both.
How does the Parker pressure range compare with AirTAC?
Closer than the Festo comparison. Parker's P1F runs 1 to 10 bar and the AirTAC SAI runs 1.5 to 10 bar, so the ceiling is identical and only the floor rises, by 0.5 bar. That matters solely for circuits that need to actuate below 1.5 bar. By contrast the Festo DSBC is wider at both ends (about 0.4 to 12 bar), so a Festo swap loses margin at the top as well.
Do I need to change the seal when substituting Parker with AirTAC?
No. Parker's P1F uses polyurethane as standard and the AirTAC SAI uses TPU, which is the same class of material, so there is no seal change to specify. This differs from an SMC swap, where SMC ships NBR as standard and you order the AirTAC's NBR option to match.
What is the piston rod difference?
Parker's standard piston rod on the P1F is austenitic stainless steel; the AirTAC SAI's is carbon steel. This is the one difference on this pair that you cannot fix by choosing an option on the AirTAC side, so it matters if the cylinder sits in a wet, washdown or otherwise corrosive location. Call the rod material out explicitly when you enquire.
