4 Inch Clay to PVC Flexible Connector Tight Fit | VIPSeal | VAC1362

Description

The VIPSeal VAC1362 flexible connector is a flexible 4 inch clay to PVC connector designed to join compatible clay drainage pipe to 110mm PVC underground drainage. This 121-136mm to 100-115mm adaptor has a narrower plastic-side range than the standard VAC4000, making it a useful tight fit drainage connector and durable EPDM clay pipe adaptor for repairs, alterations and replacement drainage work. VIPSeal manufactures VAC1362 as a step-moulded adaptor coupling for pipes with significantly different outside diameters. The larger end accepts pipe measuring 121–136mm externally, while the smaller end accepts pipe measuring 100–115mm externally.

VIPSeal VAC1362 Flexible Connector

The VIPSeal VAC1362 flexible connector is the genuine manufacturer reference for this tighter-fit adaptor within VIPSeal’s VAC flexible coupling range. The VIPSeal VAC1362 flexible connector measures 100mm in overall coupling width and uses two independently tightened stainless-steel tension bands to secure the EPDM body around both pipe ends.

Choosing the VIPSeal VAC1362 Flexible Connector

Choose the VIPSeal VAC1362 flexible connector where the larger pipe outside diameter is between 121mm and 136mm and the smaller pipe measures between 100mm and 115mm. Always measure both pipes before ordering because clay pipe dimensions can vary with age, manufacturer and construction.

4 Inch Clay to PVC Connector

The 4 inch clay to PVC connector is commonly used to transition from existing clay drainage into modern 110mm PVC-U underground drainage pipe. This makes the 4 inch clay to PVC connector useful where a damaged or outdated section of clay drainage is being repaired, extended or partly replaced with plastic pipework.

Installing a 4 Inch Clay to PVC Connector

Before fitting the 4 inch clay to PVC connector, expose a sound section of both pipes and measure their actual outside diameters. The larger pipe must measure 121–136mm and the smaller pipe must measure 100–115mm. Avoid measuring over sockets or damaged sections because these areas may be larger or uneven.

121-136mm to 100-115mm Adaptor

The 121-136mm to 100-115mm adaptor bridges the difference between two pipe outside diameters using a step-moulded flexible EPDM body. The larger 121–136mm side is suited to compatible clay and similar pipework, while the 100–115mm smaller side provides the tighter connection around compatible 110mm PVC drainage pipe.

Selecting a 121-136mm to 100-115mm Adaptor

When choosing the 121-136mm to 100-115mm adaptor, actual outside diameter is more important than nominal pipe description. Two pipes may both be described as 4 inch or 110mm while having different external measurements, particularly when older clay systems are involved.

Tight Fit Drainage Connector

The key feature of VAC1362 is its narrower 100–115mm smaller connection, which makes it a tight fit drainage connector for compatible 110mm PVC pipe. This differs from VIPSeal VAC4000, which uses a wider 110–121mm smaller connection. The tight fit drainage connector should therefore be selected where the actual plastic pipe diameter falls within the VAC1362 range.

VAC1362 Tight Fit Drainage Connector

The VIPSeal VAC1362 flexible connector provides the tighter smaller-side fit within this clay-to-plastic application. Measure the PVC pipe before ordering to make sure VAC1362 is the correct adaptor rather than the wider VAC4000.

EPDM Clay Pipe Adaptor

VIPSeal manufactures the VAC range from EPDM rubber, making VAC1362 a flexible EPDM clay pipe adaptor rather than a rigid plastic reducer. The step-moulded EPDM clay pipe adaptor allows pipes with substantially different outside diameters to be joined while the stainless-steel bands secure each end independently.

EPDM Clay Pipe Adaptor Construction

The flexible EPDM body provides the compliance required to form around compatible pipe surfaces. Stainless-steel tension bands secure the fitting at both ends.

Using the VIPSeal VAC1362 Flexible Connector

The VIPSeal VAC1362 flexible connector is particularly useful when repairing older underground drainage where a clay pipe needs to transition into modern plastic drainage. Its stepped construction eliminates the need to build up the smaller pipe using separate bushes or improvised packing when both pipe diameters fall within the specified ranges.

100mm Wide Step-Moulded Adaptor

VIPSeal specifies an overall width of 100mm for VAC1362. The stepped moulding reduces the diameter between the clay-side and PVC-side connections within one flexible adaptor body.

6Nm Tightening Torque

VIPSeal specifies a tightening torque of 6Nm for VAC adaptor couplings within this diameter range. Both tension bands should be tightened evenly using a suitable torque-controlled tool.

0.6 Bar Pressure Rating

VIPSeal gives the VAC adaptor coupling range a pressure rating of 0.6 bar / 8.7psi. The fitting is intended for drainage and other suitable low-pressure applications rather than general high-pressure pipework.

120 Bar Jetting Resistance

VIPSeal publishes a 120 bar jetting resistance for its VAC adaptor coupling range. This jetting-resistance figure should not be confused with the significantly lower internal working-pressure rating.

Working Temperature Range

VIPSeal specifies a constant working temperature range of -10°C to +60°C for VAC adaptor couplings.

VIPSeal VAC1362 Flexible Connector Applications

The VIPSeal VAC1362 flexible connector can be used for suitable applications including:

• 4 inch clay to 110mm PVC drainage connections
• Replacing damaged sections of clay drainage
• Underground drainage alterations
• Extending clay drainage with plastic pipe
• Clay-to-plastic drainage repairs
• Joining pipes with different outside diameters

VAC1362 vs VAC4000

Choose VAC1362 where the smaller pipe measures 100–115mm. Choose VAC4000 where the smaller pipe requires the wider 110–121mm connection range. Both fittings accept 121–136mm on the larger side, so measuring the smaller pipe accurately is what determines which adaptor is appropriate.
