3G Shielding Specialties Introduces No-Charge EMI Shielding Cross-Reference Service
Oct 18, 2026
3G Shielding Specialties announced a no-charge engineering cross-reference service that matches competitor EMI gaskets, PCB shield cans, RF absorbers and thermal materials by specification, typically returning a matched equivalent the same business day with free 48-hour samples.
Oceanside, United States, October 18, 2026 -- 3G Shielding Specialties, a US manufacturer of EMI and RF shielding products since 1994, today announced a no-charge engineering cross-reference service that helps electronics teams find specification-matched equivalents for EMI gaskets, board-level shields, RF and microwave absorbers and thermal interface materials already designed into their products.
Design and procurement teams in aerospace, defense, medical, telecom and industrial electronics increasingly need a qualified second source for their shielding parts. Extended lead times, allocation on popular materials and discontinued product lines — such as the W.L. Gore GS2100, GS5200 and GS8000 conductive gasket materials — can leave a single gasket or shield can holding up an entire build. Switching suppliers has traditionally meant weeks of back-and-forth before a usable equivalent reaches the bench.
Under the new service, an engineer sends 3G the competitor part number, drawing or data sheet. 3G’s US-based applications engineers then match the part by specification rather than by trade name. For conductive elastomer gaskets that means the filler system, base polymer, durometer, profile and MIL-DTL-83528 type; for fabric-over-foam and wire-based gaskets, the construction, closure force and mating-surface compatibility; for PCB shield cans, the footprint, height, material, thickness and attachment method; and for absorbers, the frequency band and loss mechanism. A matched 3G equivalent is typically returned the same business day, and evaluation samples of standard materials ship free within 48 hours.
“Engineers don’t want a trade-name substitution that fails at the test lab — they want a part that drops into the design they already qualified,” said [Spokesperson Name], [Title] at 3G Shielding Specialties. “By matching on specification and putting a free sample on the bench in 48 hours, we can help a team add a qualified alternate in days instead of reopening an EMC test campaign.”
The service covers the main families of EMI shielding: conductive elastomer, fabric-over-foam, knitted wire, oriented wire, conductive foam and form-in-place gaskets under the WaveSeal line; one-piece, two-piece, off-the-shelf, multi-cavity and hybrid PCB shield cans under 3G MetalworX; Wavexorb cavity-resonance, narrowband, surface-wave and broadband absorbers; and Thermaworx thermal gap pads. To make the process transparent, 3G has published an EMI gasket cross-reference guide that maps widely used competitor product families — including those from Parker Chomerics, Laird, Tech-Etch, MAJR Products and W.L. Gore — to their 3G equivalents, together with new engineering guides to EMI shielding, RF shielding and PCB shield can selection.
Where a competitor part has no like-for-like 3G equivalent, the company’s engineers say so up front and recommend an engineering-reviewed alternative, so that buyers can make a decision with complete information.
Documentation support is part of the service. 3G Shielding Specialties is ITAR registered, JOSCAR registered and ISO 9001:2015 certified, and supplies certificates of conformance and material traceability on request to support customer requalification packages. Controlled drawings for defense programs are handled directly by its US-based team.
Engineers can submit a part number for cross-reference or request free samples at 3gshielding.com.

Japan drop table tennis star Mima Ito, could axe Sora Matsushima-Miwa Harimoto partnership
Former Olympic champion Mima Ito has been dropped from Japan’s latest national table tennis squad, replaced by 28-year-old breakthrough player Hitomi Sato, who finished runner-up at the recent WTT China Smash. Across the border, meanwhile, followers of rival powerhouses China have focused their attention on widely circulated Chinese media reports that the Japan Table Tennis Association plans to dismantle the high-profile mixed-doubles pairing of Sora Matsushima and Miwa Harimoto. Under the...
Asian Cup football remains on track but golf, cycling events affected after Saudi attack
Golf’s Asian Tour has postponed the Saudi International indefinitely and cycling’s Urban World Championships have been cancelled following a deadly attack on Riyadh, although local organisers said next year’s Asian Cup football tournament remained on track. Yemen’s Iran-aligned Houthi movement claimed responsibility for Saturday’s strike on Riyadh’s international airport that killed at least 12 people and wounded more than 300. The Urban Cycling World Championships had been scheduled for...
World Fencing League bringing sport’s best and brightest to Hong Kong in April
Hong Kong will host a World Fencing League event next year, bringing the sport’s best and brightest to the city for one day in April, sources have told the South China Morning Post. The brainchild of 2016 US Olympic team foil bronze medallist Miles Chamley-Watson, WFL staged its inaugural event in Los Angeles earlier this year, and featured the likes of Hong Kong’s Ryan Choi Chun-yin, who captained Team Shield. Sources said the league was being pencilled in for the penultimate week of April, a...
Chad Schofield optimistic Tempted has what it takes to dethrone Ka Ying Rising in The Everest
Chad Schofield rates Ka Ying Rising “probably one of the best we’ve ever seen”, but the former Hong Kong-based jockey is confident his The Everest mount Tempted has what it takes to beat the world’s best galloper at Randwick on Saturday. Hong Kong champion Ka Ying Rising chases a 22nd straight victory in the world’s richest turf race, but a rain-affected track and Tempted’s hot form has boosted Schofield’s confidence. Since running second to Ka Ying Rising in The Everest (1,200m) 12 months ago,...
Hong Kong Olympian wonders if AI is the answer to recapturing our humanity
The 0.1 second that stood between Yvette Kong Man-yi and qualifying for the 2012 Olympics was “unbearable”, the Hong Kong swimmer writes in her newly published memoir, The Unmeasured Human. It was, the 33-year-old recalls years later, “too small to feel and too large to survive unchanged”. Fourteen years on, Kong is grateful for the heartbreaking experience, telling the South China Morning Post that “challenge is fundamental to human growth and spirit”. “I needed to find the courage to try again...

AFC Champions League 2: Hong Kong’s Tai Po ‘cross a line’ but fail to tame Lion City Sailors
Streetwise Lion City Sailors condemned Tai Po to a 1-0 AFC Champions League 2 defeat at Mong Kok Stadium on Thursday, but victorious boss Mark Jackson accused the hosts of “crossing a line” in their attempts to ruffle the Singaporean team. A husk of the side that was unbeaten at home in last season’s competition, following a summer firesale, Tai Po nevertheless ran themselves into the ground in a vain attempt to recover from the blow of Matthias Phaeton’s strike shortly after half-time. While...

Frankie Lor sets Stormy Grove on path to Hong Kong Mile with Group Two Sha Tin Trophy test
Frankie Lor Fu-chuen is hoping last season’s Classic Cup winner Stormy Grove can pass his first test on the road to the Group One Hong Kong Mile when he tackles Monday’s Group Two Sha Tin Trophy (1,600m). The Toronado galloper soared from the back of the field to collect the second leg of last season’s Classic Series, before running a mighty race to finish third in the Hong Kong Derby (2,000m) behind Invincible Ibis. His season ended prematurely on his next start, however, as he bled from both...
Promising Chinese teen basketball player joins top US high school, sparking training debate
