Pacer RX-50M Range Extended Cyanoacrylate Gel – 200 Gram (7 oz) Tube

This 200 gram (7 oz) tube of Pacer RX-50M is the production volume size of Pacer’s non-sag cyanoacrylate gel. It holds ten times what the 20 gram tube does and sells individually rather than by the case, which makes it the size for a station bonding vertical or overhead joints every day. The gel fills to .020 in, the widest gap in the RX Series, and does not move once placed. It also carries the Range Extended chemistry, so it bonds plated, oily, porous, and acidic surfaces that stop a conventional cyanoacrylate.

Package Details

Full shear strength figures by substrate, the RX viscosity selector, and guidance on bonding vertical joints are on the main Pacer RX-50M Gel product page, or in the Pacer RX Series technical data sheet (PDF).

Choosing the 200 Gram Tube Over the 20 Gram

• 200 g against 20 g, ten times the material, and it sells individually rather than in a case of 10. On a per-tube basis that makes it the easier single purchase.
• This is the size for a station that bonds vertical or overhead joints every day, or a line where gel is the standing process rather than a fix for the occasional awkward part.
• Prove the bond first if you’re new to gel. Run the 20 gram tube on the actual part in the actual orientation, then move up.
• Cyanoacrylate cure is driven by moisture and an opened tube works against ambient humidity from day one. Shelf life is one year stored per the data sheet, so buying more than you consume in that window does not save money.
• A larger tube means a larger nozzle to keep clear. Cap it between uses, because a gel tube left open sets at the tip and you lose the whole nozzle rather than a drop.
• Worth knowing across the family: the gel is the only RX grade supplied in tubes. RX-100 and RX-500 come in a 1 lb bottle if you need Range Extended chemistry at volume in a liquid.

Performance in Production

• Non-sag and non-running, rated by Pacer for vertical applications. The only grade in Pacer’s cyanoacrylate line carrying that rating, which is what lets you build a station around a part that cannot lie flat.
• Enough volume to run a daily gel operation without a purchase order every other week.
• .020 in gap capability, four times RX-100 and double RX-700, which covers fit-up variation across a production run rather than requiring consistent parts.
• 2400 psi shear on steel, the highest in the RX Series. The gel consistency costs you nothing in strength.
• Substrate failure on ABS, rigid PVC, nylon, polycarbonate, SBR, and EPDM. On all six the part fails before the bond.
• Non-surface-sensitive, so plated parts and surfaces carrying oil, silicone grease, or release agent bond without a degrease and prime step in front of them.
• Because the bead stays where you place it, an operator gets time to align the part. That is the difference between a gel station and trying to run a liquid grade on a wall.
• A full .020 in gap cures from the outside in. Fixture is 1 to 5 minutes, but allow the longer end of the 15 to 30 minute range before loading a wide joint, and consider a Pacer accelerator, which Pacer recommends specifically for larger gaps.
• Not certified to MIL-A-46050C. Confirm your job requirement before standardizing a process on it, since every other RX grade holds that certification.

Common Applications

• Daily production bonding of vertical and overhead joints
• Stations built around parts that cannot be reoriented
• Production runs with inconsistent fit-up up to .020 in
• EPDM and SBR rubber, gaskets, seals, and trim at volume
• Plated parts and mold-released components straight from molding
• Polycarbonate and nylon assemblies
• Removing degrease, abrade, and prime steps from a bonding process
• Contract manufacturing calling out A-A-3097 Type II, Class 5

Frequently Asked Questions

How much is in a 200 gram tube of Pacer RX-50M Gel?

Net weight is 7 oz (200 g), ten times the 20 gram tube. Pacer does not publish a coverage figure per gram for the gel, and a placed bead uses more material than a drop of liquid would. If you need to budget material against a part count, send us the part and we’ll help you work it out from a sample.

Is the 200 gram tube the same adhesive as the 20 gram?

Yes, identical. Same non-sag gel, same non-surface-sensitive chemistry, same .020 in gap capability, same A-A-3097 Type II, Class 5 rating. Only the tube size and the order quantity change, since the 20 gram sells in a case of 10 and this sells individually.

Will Pacer RX-50M Gel stay put on a vertical surface?

Yes. Pacer rates it as a non-sag, non-running formula for vertical applications, which is a manufacturer specification rather than a technique claim. It is the only grade across Pacer’s cyanoacrylate families carrying that rating. Test in the actual part orientation before you standardize a process, since a bead that holds on a wall behaves differently overhead.

Does Pacer RX-50M Gel meet MIL-A-46050C?

No. RX-50M carries A-A-3097 Type II, Class 5 only and is the one grade in the RX Series Pacer does not certify to MIL-A-46050C. Every other RX grade holds both. If your job calls out the MIL spec you need a liquid grade, and RX-700 at 600 to 800 cP is the thickest certified option. Call us before you standardize if the part is vertical and the spec is mandatory.

Is Pacer RX-50M Gel available in a larger size than 200 gram?

Not currently. The 200 gram tube is the largest package Pacer offers in the gel. RX-100 and RX-500 are the two Range Extended grades available in a 1 lb bottle if you need the chemistry at higher volume, though both are liquids and neither is rated for vertical use. If you’re consuming gel faster than the 200 gram tube supports, call us and we’ll look at options.

How should Pacer RX-50M Gel be stored, and what is the shelf life?

Refrigerate unopened tubes for optimal results. Once opened, store in a cool, dry location away from heat sources, and keep the cap on between uses so the nozzle does not set. Stored that way, expect a one year shelf life.

What is the part number for the 200 gram Pacer RX-50M Gel?

Our SKU is PAC-FG04072. The Pacer part number is FG04072 and the UPC is 0 87093 00250 0. On older Pacer paperwork the same item shows as Pacer item number 11740045.
