The Jopevi J-21 and J-25 are portable, manual-feed pneumatic grommet machines that punch a hole in your material and set the grommet and washer in a single action, at up to 900 settings per hour. Both run on standard shop air with no electrical connection, and both use hands-free foot pedal actuation so the operator can position material with two hands and place every setting exactly where it belongs, in under a second. The J-21 covers grommets and washers up to a #4 and is the right fit for flag makers, small shops, and medium-production work. The heavier-duty J-25 extends the range up to a #6 in a single stroke, plus larger sizes in prepunched material, for commercial flags, awnings, marine canvas, and heavy industrial fabric. Both are built for the same roughly 2,500-pieces-a-week production tier, so the choice comes down to the grommet sizes and materials you run.

Portable Pneumatic Grommet Machines: Jopevi J-21 & J-25
J-21: Pneumatic Portable Air Press Grommet Machine
The Jopevi J-21 is a portable, manual-feed pneumatic grommet machine that punches a hole in your material and sets the grommet and washer in a single action. It sets Stimpson plain sheet metal grommets and washers, sizes #00 (3/16″ hole) through #4 (1/2″ hole), which makes it the ideal choice for flag manufacturers, small shops, prototyping, and medium-production manual-feed operations running about 2,500 pieces per week. Your operator will appreciate its efficient, quiet, dependable operation, along with the versatility to handle industrial fabrics of many types: nylon and polyester flag fabric, vinyl, PVC, canvas, leather, sailcloth, webbing, seatbelt material, and more. Despite its compact, lightweight footprint, the J-21 is strong enough to set through multiple layers of nylon webbing and seatbelt material, so it’s equally at home on light textile work and demanding industrial substrates.
At 900 settings per hour, the J-21 dramatically outpaces hand-punching and hand-setting and improves productivity right away. Foot pedal actuation lets the operator position material with two-handed precision for perfect placement every time, in under a second. The integrated stainless steel work plate regulates back space and the distance between settings, so consistent placement is effortless. A built-in finger guard prevents the machine from cycling when the dies are obstructed, which keeps the operator safe through a long run. Setting dies swap out and adjust easily for different grommet sizes and material thicknesses, and the J-21 can also be set up to simply punch holes or set the grommet alone.

J-25: Heavy-Duty Pneumatic Portable Air Press Grommet Machine
The Jopevi J-25 is a heavy-duty, portable, manual-feed pneumatic grommet machine that punches a hole in your material and sets the grommet and washer in a single action. It has a cut-and-set capacity of size #00 plain sheet metal through #6 rolled rim grommets and spur washers (3/4″ hole) in a single stroke, plus a set-only capacity in prepunched material of #7, #8, and #10 rolled rim grommets or curtain grommets. That broad range makes the J-25 the right choice for commercial flags, awnings, marine canvas, banners, industrial tarpaulins, heavy webbing, and any medium-production manual-feed operation running about 2,500 pieces per week. Your operator will appreciate its efficient, quiet operation and its versatility across industrial fabrics: 2-ply polyester and nylon flag fabric, canvas, vinyl, PVC, sailcloth and marine fabrics, leather, webbing, seatbelt material, and more. The J-25 is strong enough to set through multiple layers of nylon webbing and seatbelt material, yet portable enough to move between workstations as production demands.
At 900 settings per hour, the J-25 dramatically outpaces hand-punching and hand-setting and improves productivity right away. Foot pedal actuation lets the operator position material with two-handed precision for perfect placement every time, in under a second.

A built-in finger guard prevents the machine from cycling when the dies are obstructed, which keeps the operator safe through a long run. Setting dies swap out and adjust easily for different grommet sizes and material thicknesses, which gives the J-25 a wide setting range without committing to a fully automatic machine.

Frequently Asked Questions
What’s the difference between the J-21 and the J-25?
The J-21 sets grommets and washers up to a #4 and suits flags and general fabric work. The J-25 is the heavy-duty version: it cuts and sets up to a #6 in one stroke, sets #7, #8, and #10 in prepunched material, and handles curtain grommets, so it’s built for awnings, marine canvas, and heavier industrial fabric. Both run at 900 settings per hour.
What size grommets does the J-21 set?
The J-21 sets Stimpson plain sheet metal grommets and washers from #00 (3/16″ hole) through #4 (1/2″ hole). For larger sizes, step up to the J-25.
Do these machines need electricity?
No. Both the J-21 and J-25 run on standard 120 psi shop air. You only need a compressor, not an electrical connection.
How fast are they?
Both set up to 900 grommets per hour, well beyond hand-punching and hand-setting.
Can the J-25 set curtain grommets?
Yes. The J-25 sets #7, #8, and #10 rolled rim grommets and curtain grommets in prepunched material, in addition to its cut-and-set range up to a #6.
What materials can they handle?
Both are built for industrial fabrics: flag material, canvas, vinyl, PVC, sailcloth and marine fabrics, leather, webbing, and seatbelt material. Both are strong enough to set through multiple layers of nylon webbing.
