Fastest Way to Join Ductile Iron Fittings
The T-type joint is the industry standard for speed. Lubricate the gasket. Push the pipe into the socket. That is it. No bolts to tighten. No flanges to align. No welding. Your crew installs fittings in minutes.

No Special Tools Required
Your crew already knows how to assemble T-type joints. Same lubricant. Same push-on motion. Same depth marking. The fittings work exactly like standard T-type pipe joints. No training needed.

Built to Match Your Ductile Iron Pipes
We cast these fittings from the same ductile iron grade as your pipes. Same strength (400 MPa tensile). Same elongation (15%). Same corrosion resistance. The fitting and pipe behave as one unit.

Flexible Joint Handles Ground Movement
The T-type rubber gasket allows angular deflection. The pipe can bend at the joint. This protects your pipeline during ground settlement and seismic events. The rubber seal flexes without leaking.

Simple Rubber Gasket Does the Sealing
One EPDM gasket per joint. No complicated sealing mechanisms. The gasket compresses as you push the pipe in. It seals against internal pressure and external soil pressure. It also seals against vacuum.

 

 

Buried Water Distribution Mains – Most buried water pipelines use T-type joints. The soil provides passive resistance for thrust. Concrete thrust blocks at bends and tees are standard practice.

Gravity Sewer Lines – No internal pressure. T-type joints are perfect. The gasket seals against groundwater infiltration. The joint allows deflection for trench alignment.

Low-Pressure Irrigation Mains – PN10 or PN6 lines. T-type fittings save money. No need for expensive restrained joints or flanges.

Treatment Plant Gravity Piping – Inside the plant but buried or in trenches. T-type joints install fast. They allow for minor alignment adjustments.

Temporary Bypass Lines – Quick assembly and disassembly. T-type joints come apart with a simple puller tool. No bolts to rust.

Raw Water Intake Lines – Large diameter pipes from rivers or lakes. T-type joints seal reliably under vacuum and low pressure.

Cooling Water Return Lines – No need for restrained joints on low-pressure return lines. T-type fittings do the job at lower cost.

Fire Water Storage Tank Fill Lines – Gravity flow from tanks to pumps. T-type joints are sufficient.

 

 

Component	Material	Key Property
Fitting body	Ductile iron EN-GJS-400-15	400 MPa tensile, 15% elongation
Rubber gasket	EPDM (standard)	Shore A 70-75, drinking water approved
Gasket retainer (if used)	Ductile iron or stainless steel	Keeps gasket in position
Lubricant (supplied)	Water-based, non-toxic	Safe for drinking water

 

 

EPDM Gaskets – One per joint. Supplied with each fitting. Pre-lubricated or dry (your choice). Drinking water approved (WRAS, NSF, or ACS).

Gasket Lubricant – Water-based, non-toxic. One 1kg tub per 50 joints. Do not use petroleum-based grease. It damages EPDM.

Depth Marking Gauge – Tool for marking insertion depth on the pipe. Wrap-around style. Works on all pipe diameters.

Insertion Marking Paint – Bright color paint. Marks the pipe at the correct depth. Visible during push-on assembly.

 

 

Pipe Puller Tool – For separating T-type joints during maintenance. Mechanical or hydraulic. Fits over the pipe and pushes against the socket.

Flanged Adaptor (T-Type on One End, Flanged on Other) – Connect T-type pipeline to pumps, valves, or equipment.

T-Type to Plain Pipe Adaptor – For connecting T-type fittings to plain pipe ends without cutting.

Thrust Block Design Chart – Free with every order. Shows concrete volume needed for each bend angle, pipe size, and pressure.

Spare Gasket Kit – Extra gaskets for field use. Store in cool, dry place. Do not expose to sunlight.

Stainless Steel Gasket Retainer – For high-pressure or vacuum service. Keeps gasket from rolling out during assembly.

 

Hydrostatic Shell Test – Water pressure at 1.5x rating. No leaks through casting. 60 second hold.

Material Tensile Test – Sample from each melt. Must achieve 400 MPa and 15% elongation.

Lining Thickness Test – 6 points per fitting. Must meet EN 545 or EN 598 minimums.

Dimensional Check – Socket inner diameter, gasket groove depth, stop shoulder position. All must be within tolerance.

Marking Check – Each fitting marked with DN, PN, heat number, and standard. Permanent marking.
