The German DIN 3771 standard refers to all O-rings as sealing elements for fluid technology and identifies O-Ring sizes by their Inner Diameter (ID) &Cross Section (C/S). This standard has essentially been incorporated into the international standard ISO 3601 which sets the globally relevant O-ring dimensions and uniform rules for installation spaces and the properties of the O-rings. It defines metric O-rings according to the same dimension chart as DIN 3771 while it has been extended to include O-rings in imperial dimensions. ISO 3601 also goes beyond the German standard in the area of materials containing material requirements for O-rings that far exceed those of DIN 3771.

Elastomer materials suitable for certain sealing situations are referred to by their abbreviation according to DIN ISO 1629 and include: 

Nitrile/Buna-N (NBR), presently the seal industry’s most widely used elastometer, Ethylene-Propylene (EPM/EPDM) used extensively for outdoor, weather-resistant uses and water applications, 

Silicone (MQ, PMQ, VMQ, PVMQ) especially resistant to high, dry heat in primarily static applications, 

Neoprene® (Chloroprene) (CR) developed as oil-resistant substitute for natural rubber with resistance to ammonia and Freon® and therefore a superior sealing material for the refrigeration industry, 

Fluorocarbon compounds (FPM / Viton®) / (Fluorel®) (FKM) combining high-temperature toughness with wide chemical agent compatibility, and 

Fluorosilicone (FVMQ) combining the good high and low temperature stability of silicones with the fuel, oil and solvent resistance of fluorocarbons.

ISO 3601 / DIN 3771 standard O-rings are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are supplied in competitively priced packs in different materials, sizes, and hardnesses as specified by a two-digit Shore A durometer number,ranging from 20 (soft) to 90 (hard), depending on the type of elastomer.

CHAMPION AEROSPACE designs and manufactures CHAMPION-brand filters and piston-engine ignition components for both OEM and aftermarket for general aviation aircraft applications.

CHAMPION FAA/PMA Approved Spin-On Oil Filters replace oil filter elements. They are easy to install and save time and clean-up.

Their full-pleat, resin-impregnated micronic filter media traps all harmful particles, including metallic chips which result from abnormal engine wear. Because the oil flows through many layers of locked-in fibers, there is no migration of fiber material to clog engine oil passages or affect bearing surfaces. According to industry-approved tests, the CHAMPION oil filters trap and hold more dirt and harmful particles during their normal operating time than any other similar filters. 

Product Features:

Replacement elements service engine-mounted or line-installed filter systems incorporating a permanent housing assembly.

All sizes of replacement elements are packed 12 per case of a single part number in heavy, re-shippable corrugated-board cartons

Modern spin-on oil filters contain the element, incorporating the anti-drain back valve mechanism (and internal bypass valve 48108-1/48109-1), and are sealed in a disposable housing.

All sizes of spin-on filters are packed 12 per case of a single part number in heavy, re-shippable corrugated-board cartons.

Silicone impregnated filter gasket aids in future removal.

Shorter stud length on CH 48110-1 for tight clearance applications.

Heavy, corrugated steel center tube supports each convoluted pleat of the filter element and produces a substantially higher collapse-pressure rating, twice that of other similar filters.

Maximum full-flow design, without interference from center-bolt oil filter assemblies, provides increased oil filtration each engine-operating hour.

Sold each or in packs of 12 filters per pack.

TRONAIR® is a leading GSE manufacturer offering a diverse range of high-quality GSE product lines to support safe and efficient aircraft ground operations. Their product portfolio includes equipment for jacking & access, hydraulic & pressure testing, towing & taxiing, electrical power & air conditioning, and aircraft & engine servicing.

TRONAIR® ATA-29 Hydraulic Power Service Units (HPUs) are multipurpose equipment, used for loading hydraulic oil in the aircraft or engine tanks of commercial, regional, and business airlines or allowing the aircraft actuators to be moved through their equipped high-pressure pumps. Their filter lines ensure that the liquid is not contaminated while their use reduces aircraft filter changes and increases aircraft component life. TRONAIR® ATA 29 HPUs have the best high-grade filtration in the industry. TRONAIR® HPUs are available in different series and various configurations. Despite their differences all HPUs are powered by a motor (the primary source of power), which in turn powers the main pump to circulate hydraulic fluid from the reservoir throughout the entire system. Typically, motors are electrically powered. However, a few are gas and diesel-driven for outdoor usage. Other HPU components include the hydraulic pump which controls both the flow and the pressure within the unit, the reservoir (the storage area for the hydraulic fluid), the regulators which control or "regulate" the pressure lines and the relief and pressure supply lines which keep the pressure inside the hydraulic power unit level.

TRONAIR® Reservoir Service Units, under their Hydraulic Service Units product range, support control of contamination of hydraulic fluids from dirt, air, and water in aircraft hydraulic systems through the servicing process. Re-circulating the fluid, prior to servicing, removes particulate contamination from the servicing line and couplings through their 2 micron filter and air, visible in their transparent return hose. Pressure and vacuum valves in the reservoir fill cap minimize tank breathing and thereby control the entry of water into the fluid. TRONAIR® Reservoir Service Units feature a 2 gallon (7.6 liter) reservoir capacity and a maximum output pressure rating of 75 psi/5.2 bars or 200 psi/13.8 bars depending on the model. Units are shipped fully assembled with the exception of customer supplied quick-disconnect couplings. 

For more information please consult the supplied documentation. 

Note: TRONAIR® ATA-29 Hydraulic Power Service Units (HPUs) are offered with or without CE marking (*). Listed HPUs are non CE rated. For CE rated versions please specify during ordering. 

(*) CE marking indicates that a product has been assessed by the manufacturer and deemed to meet EU safety, health and environmental protection requirements. It is required for products manufactured anywhere in the world that are marketed in the EU.
