Detroit Oil Suction Manifold Seal DDE

Product Overview

The Detroit oil suction manifold seal is the rubber sealing element that closes the joint where the oil suction manifold feed pipe meets the engine. It works on the suction side of the oil circuit, where a hardened or weeping seal shows up as oil around the pipe — and, in worse cases, as air drawn into the oil before it ever reaches the pump.

Fleet workshops, engine rebuilders and parts distributors working on Mercedes-Benz, Freightliner, Setra, Deutz-Fahr and Western Star vehicles fit this seal as a straight service replacement. It is moulded to OEM dimensions, so it seats in the same groove and takes the same clamping load as the part that comes off. As an automotive components manufacturer, we produce it in the same rubber family as the gaskets and O-rings that surround it in the oil circuit, which lets a distributor cover a full feed pipe repair from one supply line.

Specifications

Vehicle Coverage

• Mercedes-Benz — Actros MP4 / MP5 from 2011/07, Antos 2012/07–2018/12, Arocs from 2013/01 and Travego (O 580) from 1999/10.
• Freightliner — Century from 1995/01.
• Setra and Western Star — Setra Series 400 from 2001/06 and Series 500 from 2012/01; Western Star 4800 from 1985/01 and 5800 from 2004/01.
• Deutz-Fahr — Series 11 from 2014/09.
• Match the reference first — the number on the old seal is the quickest way to keep a mixed-brand auto parts order accurate when one engine family is sold under several model names.
• List upkeep — as an automotive components manufacturer we tie every platform entry to its OEM reference, so a renamed or superseded model does not send a workshop to the wrong seal.

Material & Sealing Performance

Moulded rubber is what lets this seal work where a cut gasket struggles. Unlike a fibre truck gasket, the compound compresses into the flange under clamping load and recovers as the joint moves through warm-up and cool-down, so the feed pipe stays oil-tight instead of slowly loosening its grip.

Three things follow from that construction. The seal tolerates the light surface marks left on a used flange far better than a hard material will. It keeps its shape in continuous contact with hot engine oil, which is the condition it lives in. And on true faces it needs no sealant at all — on the suction side, excess compound working loose into the oil path is a repair nobody wants to repeat.

When the manifold is apart, replace the seals and O-rings along the same pipe in the same visit. A second teardown costs far more than the small parts it saves.

Fitting Position & Installation

1. Confirm the reference — compare the number on the old seal with the OEM reference for your engine before the pipe is disturbed.
2. Clean both faces — remove old seal residue, oil film and loose corrosion from the feed pipe and the manifold flange.
3. Inspect for damage — a scored or pitted flange will not seal against any rubber, so dress or replace the mating part first.
4. Seat the seal square — press it onto the feed pipe without stretching it, and fit it dry unless the engine maker's procedure specifies a sealant.
5. Torque to the engine maker's figure — the value depends on the pipe and fasteners on your unit, so follow the workshop manual rather than a generic number.
6. Run and re-check — bring the engine to temperature and inspect the joint for weeping before the vehicle goes back into service.
