Product Description

VIP Electrical Conduit Collar (Coupler) is a precision-engineered joining fitting manufactured by VIP Extrusions, designed to seamlessly connect two conduit pipes and extend your electrical conduit runs. The HMS (Heavy Mechanical Stress) grade construction ensures superior joint strength and impact resistance, making it ideal for demanding installations where reliability is critical.

Combining injection molding precision with hand-crafted finishing for perfect color matching, these couplers feature FRLS properties for enhanced fire safety compliance. The lightweight design facilitates easy installation while the smooth internal bore ensures unobstructed cable pulling. Being non-metallic and non-corrosive, these collars provide long-lasting, maintenance-free performance in all electrical applications.

Recommended Applications

• Conduit Extension: Joining 3-metre conduit pipes to create longer continuous runs
• Industrial Installations: Heavy-duty HMS grade for factories, warehouses, and high-stress environments
• Commercial Buildings: Office spaces, retail stores, and commercial complexes requiring reliable connections
• Residential Wiring: Concealed and surface conduit systems in homes and apartments
• Repair & Maintenance: Replacing damaged conduit sections or extending existing installations
• Multi-Story Buildings: Long vertical and horizontal conduit runs requiring multiple joints

Installation Guidelines

FAQs

1) What is the difference between a collar and a coupler?

Collar and coupler are the same product with different names used interchangeably in the industry. Both refer to a straight joining fitting that connects two conduit pipes end-to-end to extend the conduit run. VIP uses the term "collar" but the function is identical to a coupler.

2) Why is HMS grade important for couplers?

HMS (Heavy Mechanical Stress) grade couplers have thicker walls and higher impact resistance, ensuring stronger joints that won't crack under stress. This is critical because joints are potential weak points in conduit systems. HMS grade provides extra durability in high-traffic areas, industrial settings, or installations subject to vibration or impact.

3) How do I ensure a leak-proof solvent joint?

For leak-proof joints: (1) Clean and deburr pipe ends thoroughly, (2) Apply solvent generously to both surfaces, (3) Insert pipes fully into the collar with a slight twisting motion, (4) Hold firmly for 30 seconds, and (5) Allow 24 hours curing time before cable pulling. Avoid disturbing the joint during curing.

4) Can I reuse a collar if I need to disconnect pipes?

No, solvent-welded joints are permanent and cannot be disconnected without cutting. Once solvent cement cures, it chemically fuses the UPVC surfaces together. If you need to disconnect, you must cut the conduit and use a new collar to rejoin. Plan your conduit layout carefully before cementing.

5) How many collars will I need for my installation?

Calculate based on your total conduit length: one collar per 3-metre pipe joint. For example, a 15-metre run requires 5 pipes and 4 collars. Always purchase 10-15% extra collars as spares for mistakes, future repairs, or unexpected layout changes during installation.

6) Should I support the conduit near collar joints?

Yes, always install support saddles within 300mm (12 inches) on both sides of each collar joint. This prevents stress concentration at the joint and maintains alignment. Unsupported joints can sag or twist over time, potentially causing joint failure, especially in horizontal runs or when pulling heavy cables.

7) Are VIP collars compatible with other conduit brands?

While VIP collars follow standard sizing, we strongly recommend using VIP collars with VIP conduit pipes for guaranteed compatibility. VIP collars are hand-crafted from VIP conduits to ensure perfect color matching, optimal fit, and strongest solvent joints. Mixing brands may result in poor fit or weak joints.
