Tlhaloso:
Valve ea heke ea EZ Series Resilient seated NRS ke valve ea heke ea wedge le mofuta oa kutu e sa phahamiseng, 'me e loketse ho sebelisoa le metsi le maro a sa nke lehlakore (likhoerekhoere).
Tšobotsi:
-Ho nkela tiiso e ka hodimo sebaka inthaneteng: Ho e kenya le ho e hlokomela habonolo.
-Disiki e kopaneng e koahetsoeng ka rabara: Mosebetsi wa foreimi ya tshepe e ductile o kwahetswe ka mocheso ka botlalo ka rabara e sebetsang hantle. Ho netefatsa ho kwalwa ka thata le thibelo ya mafome.
-Nate ea koporo e kopantsoeng: Ka mokhoa o ikhethileng oa ho lahla. Nate ea kutu ea koporo e kopantsoe le diski ka khokahano e sireletsehileng, kahoo lihlahisoa li bolokehile ebile lia tšepahala.
-Setulo se bataletseng se ka tlase: Sebaka se tiileng sa ho kwala sa mmele se bataletse ntle le sekoti, ho qoba ho tsholoha ha mobu.
-Mokana wa phallo o phallang ka botlalo: kanale yohle ya phallo e feta, e leng se etsang hore kgatello e lahlehe "lefela".
-Ho tiisa ka holimo ho ka tšeptjoang: ka sebopeho sa lesale la multi-O se amohetsoeng, ho tiisa hoa tšepahala.
-Sekoahelo sa resin ea epoxy: polasitiki e fafatsoa ka sekoahelo sa resin ea epoxy kahare le kantle, 'me li-dic li koahetsoe ka rabara ka botlalo ho latela tlhoko ea bohloeki ba lijo, kahoo e bolokehile ebile e hanela mafome.
Kopo:
Sistimi ea phepelo ea metsi, kalafo ea metsi, ho lahla likhoerekhoere, ts'ebetso ea lijo, sistimi ea tšireletso ea mollo, khase ea tlhaho, sistimi ea khase e metsi jj.
