3M™ E-A-R™ TaperFit™ 2 Earplugs | Regular Uncorded | Class 5 SLC80 26dB | 312-1219

Soft Roll-Down Foam Hearing Protection with High Attenuation and Low-Pressure Comfort

Supply Solutions Group supplies 3M™ E-A-R™ TaperFit™ 2 Regular Uncorded Earplugs – Class 5, SLC80 26dB – 312-1219 to organisations operating across mining, construction, manufacturing, engineering, transport, utilities, maintenance and industrial workplaces throughout Australia.

The 3M E-A-R TaperFit 2 Regular Uncorded Earplug is a disposable roll-down foam hearing protector designed to provide high levels of noise attenuation while maintaining comfortable, low-pressure contact within the ear canal.

Manufactured by 3M, the TaperFit 2 uses soft foam construction that is compressed before insertion and then expands inside the ear canal to create a secure acoustic seal.

The tapered shape helps the plug conform to different ear-canal profiles while providing a comfortable fit during extended workplace use.

Australian 3M technical data confirms the Regular Uncorded model provides:

SLC80 26dB – Class 5

This places the product in the highest hearing-protector class under the Australian SLC80 classification system.

The earplugs are suitable for appropriate high-noise workplace environments where the required hearing protection is determined by a workplace noise assessment.

Typical applications include:

• Mining

• Manufacturing

• Construction

• Engineering

• Heavy equipment

• Workshops

• Industrial maintenance

• Transport operations

The 312-1219 is the Regular Size, Uncorded configuration.

3M also offers a larger TaperFit 2 version for workers who require a larger earplug size.

Each pair is supplied in a poly bag, helping keep the earplugs clean before use.

The uncorded design is particularly convenient where workers prefer individual plugs without a connecting cord.

3M states that TaperFit 2 earplugs may also be used with appropriate earmuffs for additional hearing protection, where a workplace hearing-protection assessment requires dual protection.

The product is compatible with the 3M E-A-Rfit Dual-Ear Validation System, enabling workplaces to quantitatively assess the noise reduction achieved by an individual wearer.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides 3M hearing protection, earplugs, earmuffs, respiratory PPE, safety eyewear and industrial consumables backed by responsive customer service, procurement support and Australia-wide business supply capability.

Why Choose 3M™ E-A-R™ TaperFit™ 2 Earplugs?

The 3M TaperFit 2 combines Class 5 hearing protection with a soft, low-pressure foam design.

Workers in high-noise environments may need to wear hearing protection for substantial periods throughout a shift.

Comfort therefore plays an important role in encouraging consistent use.

The TaperFit 2 is designed to expand gently inside the ear canal while providing a reliable acoustic seal.

Class 5 Hearing Protection

The Regular Uncorded TaperFit 2 provides:

SLC80 26dB – Class 5

Class 5 is the highest SLC80 hearing-protector class used in Australia.

This does not mean the earplug is automatically appropriate for every noise environment.

Hearing protection should be selected according to:

• Measured workplace noise

• Exposure duration

• Required attenuation

• Individual fit

• Applicable workplace procedures

SLC80 26dB

SLC80 stands for Sound Level Conversion, with 80% confidence.

The TaperFit 2 Regular model is rated:

26dB SLC80

The actual protection achieved by an individual worker can vary depending on insertion technique and fit.

This is why correct fitting and, where appropriate, individual fit testing are important.

Soft Roll-Down Foam

The earplug is manufactured from soft foam.

To fit the plug, the wearer rolls the foam into a narrow cylinder before insertion.

Once inserted, the foam expands to conform to the ear canal.

This provides:

• Comfortable contact

• Low pressure

• Secure fit

• Effective noise attenuation

Tapered Shape

The TaperFit 2 uses a tapered profile.

3M states that this design provides:

• High attenuation

• All-day comfort

• Conformity to the unique shape of the ear canal

The tapered design can also assist insertion when the plug is correctly compressed.

Regular Size

The 312-1219 is the:

Regular Size

3M also offers a Large TaperFit 2 variant.

Providing multiple sizes can improve fit across a broader workforce because ear-canal dimensions vary between individuals.

Uncorded Design

The 312-1219 is:

Uncorded

There is no connecting cord between the two earplugs.

This design may be preferred where workers do not require a cord or where a cord could interfere with other PPE or equipment.

Individually Poly-Bagged

3M supplies each pair in a:

Poly Bag

This helps keep the earplugs clean before use.

Individual packaging is particularly practical for:

• Site PPE stations

• Visitor PPE packs

• Toolboxes

• Vehicle kits

• Workshops

• Worker issue

3M™ E-A-Rfit™ Compatibility

The TaperFit 2 is compatible with the:

3M E-A-Rfit Dual-Ear Validation System

This system allows employers to measure the level of noise reduction achieved by a specific worker wearing the hearing protector.

Individual fit testing can help identify:

• Incorrect insertion

• Poor fit

• Inappropriate earplug size

• Need for additional training

• Need for an alternative hearing protector

Can Be Used with Earmuffs

3M states that TaperFit 2 earplugs may be worn with earmuffs for additional protection. (3M Australia)

Dual protection may be required in particularly high-noise environments.

The combination should be selected through a proper workplace noise assessment rather than simply adding the numerical attenuation ratings together.

Correct Fitting

Roll-down foam earplugs rely heavily on correct insertion.

A typical fitting process includes:

1. Ensure hands are reasonably clean.

2. Roll the entire earplug into a narrow, crease-free cylinder.

3. Reach over the head and gently pull the ear upward and outward.

4. Insert the compressed plug sufficiently into the ear canal.

5. Hold the plug in place while the foam expands.

6. Check that the plug is seated correctly.

7. Repeat for the opposite ear.

Always follow the current 3M fitting instructions.

Why Proper Fit Matters

Even a Class 5 earplug may provide significantly less protection if:

• It is not rolled correctly

• It is inserted too shallowly

• The size is unsuitable

• The foam has not expanded properly

Correct fit is therefore essential to achieving effective attenuation.

Hearing Protection Selection

Hearing protection should form part of a broader workplace noise-management program.

Controls may include:

• Engineering noise controls

• Isolation

• Equipment maintenance

• Administrative controls

• Reduced exposure duration

• Hearing protection

PPE should not replace higher-level noise controls where these are reasonably practicable.

Important Hearing Safety Information

Overprotection can also create workplace issues by reducing the wearer’s ability to hear:

• Warning alarms

• Speech

• Vehicle movements

• Equipment signals

The hearing protector should therefore provide sufficient attenuation without unnecessarily isolating the worker from important audible information.
