Techcon TS618-HO-LD-1000 6 in LDPE Nozzle, 1/8 in Orifice – 1000 Pack

This Techcon TS618 nozzle 1000 pack is the bulk quantity of the 6 in natural LDPE nozzle with a 1/8 in orifice and a 1/4 in NPT male thread. The wider opening gives a larger starting bead than the 1/16 in TS616, with the same 6 in reach into recessed joints, housings, and cavities. Techcon lists these as disposable nozzles, and the tip can be cut back to open the orifice. The 1000 pack is the bulk quantity, sized for cells that reorder the same nozzle.

Key Product Details

Performance in Production

• The 6 in length (152.4 mm) puts the tip well beyond the cartridge, so a bead can reach into recessed joints and housings. Techcon’s standard nozzle line also includes 2 in and 4 in lengths for shallower work.
• The 0.125 in (3.2 mm) orifice is the wider of the two 6 in orifice sizes in Techcon’s standard line and sets a larger starting bead.
• Techcon states that standard nozzles may be cut back to increase the orifice size. Cutting only opens the orifice, so cut in small steps and test each cut on scrap.
• The 1/4 in NPT male thread mates with a matching female outlet on Techcon cartridges or equivalent. Confirm your cartridge outlet before ordering a production quantity.
• A longer tip adds flow resistance, and more so with thicker fluids. Run a trial bead with your fluid, cartridge, and dispense pressure before the nozzle goes into a work instruction.
• Techcon molds these from natural polyethylene and sells them as disposable nozzles. Confirm your fluid is compatible with polyethylene, and replace the nozzle when cured material or contamination changes the bead shape.

Common Applications

• Placing sealant, adhesive, or potting compound deep inside housings and assemblies
• Dispensing into recessed joints and seams
• Bead placement from a 6 in reach where a 1/16 in opening is too small for the fluid
• Reaching the bottom of deep cavities and channels
• Dispensing around fixtures, ribs, and part geometry that would foul a shorter nozzle
• Replacement nozzles for Techcon cartridge setups with a 1/4 in NPT outlet

How to Pick and Cut a 6 in Cartridge Nozzle

A cartridge nozzle is matched by thread, length, and orifice, and the orifice can be opened by cutting the tip. The steps below work for both the TS616 and the TS618.

1. Check the cartridge outlet. These nozzles have a 1/4 in NPT male thread, so the cartridge outlet or adapter needs a matching 1/4 in NPT female thread.
2. Pick the starting orifice. The TS616 has a 0.063 in opening and the TS618 has a 0.125 in opening. Start with the one closest to the bead you need.
3. Run a trial bead on scrap with the fluid, cartridge, and dispense pressure you plan to use.
4. If the bead is too small, cut the tip back a little at a time. Each cut opens the orifice, and a cut cannot be undone.
5. Test after every cut. Once the bead is right, write the cut position into your work instruction so every operator cuts to the same spot.
6. Replace the nozzle when cured material or contamination changes the bead shape.

The process applies to sealants, adhesives, epoxies, and potting compounds loaded in a compatible cartridge. Confirm fluid, viscosity, and pressure on your own setup before production.

Frequently Asked Questions

What is the Techcon TS618 nozzle used for?

It places adhesive, sealant, or potting compound from a compatible cartridge into joints and cavities that a short nozzle cannot reach. Techcon lists it as a standard nozzle in its disposable nozzle line, and cartridge nozzle and dispensing nozzle describe the same part. Confirm your fluid is compatible with polyethylene.

What does HO-LD mean in TS618-HO-LD-1000?

Techcon describes the HO-LD nozzles as high-output nozzles made of low-density polyethylene. The last part of the number is the pack, where PK is the 50 pack and 1000 is the 1,000 pack.

Will it fit my cartridge?

It fits Techcon cartridges or equivalent, and the nozzle end is a 1/4 in NPT male thread. A cartridge with a different outlet thread needs an adapter, so call us with the cartridge model before you order and we will confirm the fit.

Can I cut the nozzle to change the bead size?

Yes. Techcon states that standard nozzles may be cut back to increase the orifice size. Cutting only opens the orifice, so start with the 1/8 in and cut in small steps, testing on scrap after each cut. If 1/8 in is already wider than you need, the TS616 1000 pack has a narrower 0.063 in orifice.

What is the difference between the TS616 and TS618 nozzles?

Both are 6 in LDPE nozzles with the same 1/4 in NPT thread, and the orifice is the difference. The TS616 1000 pack has a 0.063 in (1.6 mm) orifice and the TS618 1000 pack has a 0.125 in (3.2 mm) orifice. Pick by the bead size and fluid you run.

What is the maximum pressure for these nozzles?

Techcon’s catalog page and store listing for this nozzle do not publish a maximum pressure. Call us before you run it on a pneumatic or pressurized dispensing system and we will confirm the limit with Techcon.

Where are these nozzles made?

Techcon’s catalog page does not state a country of origin. Call us for the country of origin on current stock.
